Methyl acetate is mainly used to replace acetone, butanone, ethyl acetate, cyclopentane and other traditional solvents. It can be miscible with most organic solvents and is widely used as industrial solvents. As a new organic solvent, methyl acetate belongs to the organic solvent which is not restricted to use in the world. It can meet the new environmental protection standards of paint, ink, resin and adhesives factories. It belongs to the green environmental protection products encouraged by the national industrial policy.

First, product characteristics

1. It can dissolve with most organic solvents.
2. It has wide solubility and can dissolve acrylic acid, vinyl, nitrocellulose, epoxy, polyurethane, polyester, phenolic resin, etc.
3. It has higher flash point and higher whitening resistance than acetone, and can better meet the requirements of coatings, paint formulations and users.
4. The application of ethyl acetate, acetone and butanone can be replaced in the process formulation requiring the use of low boiling point volatile organic solvents.
5. Polyurethane shoe materials can replace cyclopentane and chlorofluorocarbons as environmental friendly foaming agents.
6. There is a big price difference with acetone and butanone, which is conducive to the cost reduction of leather, coatings and adhesives manufacturers.
7. The solubility of nitrated sponge is similar to acetone, butanone, which is 4.5 times than that of toluene, 3.4 times than that of ethyl acetate and 2.7 times than that of butyl acetate.

Second, main uses

1. Used as an intermediate in the production of medicine and pesticides. The market basically uses methyl acetate.
2. Organic solvents needed in the production of resins, coatings, inks, paints and adhesives: methyl acetate has strong solubility and is an excellent organic solvent. As a solvent in the above industries, it has the advantage of forming a solution with lower viscosity than ethyl acetate in a certain solid component.
3. It can also be used as an oil extractant and used in the manufacture of artificial leather, etc. Methyl acetate is commonly used in the market.
4. In the application of flavor, it can be used in daily flavors, but it is mainly used in the blending of food flavors, and more refined methyl acetate is used.
5. Used to synthesize acetic acid, acetic anhydride, methyl acrylate, vinyl acetate and acetamide. High purity methyl acetate is used as organic raw material in the market.

Mesterolone Proviron Product Detail

Mesterolone (Mes-te-roh-lone) is a medicine which is used in male infertility and androgen deficiency.

Proviron (mesterolone) is an interesting anabolic steroid, though it is not of much value to bodybuilding. It seems that the most common reason for many to consider including it in a steroid stack is for anti-estrogenic activity. In the days before anti-aromatases and the use of SERMs (selective estrogen receptor modulators) such as Clomid and Nolvadex, there was some merit to this.

Mesterolone belongs to the group of medicines known as androgens, which are male sex hormones. It is used to treat disorders in men where the body does not make enough natural androgen. It works by supplementing the amount of male hormone your body produces naturally.

Mesterolone, or Proviron used in the treatment of male hypogonadism and sperm reducing infertility, it is an orally applicable androgen, and DHT derivative, is sold under the brand Mesterolone. Mesterolone cipionate was administered twice monthly, Mesterolone is a relatively weak androgen and rarely used for replacement therapies.

Mesterolone (Proviron) Application

All the information we provide is for reference only, please use drugs according to professional advice

Mesterolone is used in the treatment of androgen deficiency in male hypogonadism, anemia, and to support male fertility among other indications. It has also been used to treat delayed puberty in boys. Because it lacks estrogenic effects, mesterolone may be indicated for treating cases of androgen deficiency in which breast tenderness or gynecomastia is also present. The drug is described as a relatively weak androgen with partial activity and is rarely used for the purpose of androgen replacement therapy, but is still widely used in medicine.

Mesterolone Side Effects And Prevention

Side effects of mesterolone include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. It has no risk of liver damage. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong androgenic effects and weak anabolic effects, which make it useful for producing masculinization. The drug has no estrogenic effects

Mesterolone was discovered and introduced for medical use in 1934. In addition to its medical use, mesterolone has been used to improve physique and performance, although it is not commonly used for such purposes due to its weak anabolic effects. The drug is a controlled substance in many countries and so non-medical use is generally illicit.

Application of VAM

used in the production of polyvinyl alcohol, coatings and adhesives.It is an important organic chemical material.Vinyl acetate by its polymerization or copolymerization with other monomers,mainly use for the production of polyvinyl acetate (PVAc),polyvinyl alcohol (PVA),vinyl acetate - ethylene copolymer emulsion (VAE) or vinyl acetate copolymer (EVA) resin,vinyl chloride copolymer (EVC), acetal resins such as derivatives. These derivatives usage is very extensive and can be used for bonding agent, and glue pharmaceutical of paper or fabric, coating, ink, leather processing, fibre processing, emulsifier, water soluble film, soil conditioner,.VAM is an important synthetic material monomer. with the progress of science and technology, other downstream products and new applications are still in constant development.

Vinyl acetate is used to make other  industrial chemicals.These chemicals are used mainly to make glues for the packaging and building industries.They are also used to make paints,textiles,and paper.Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch.

Physical properties of VAM

Melting point: -93 °C

Boiling point: 72-73 °C (lit.)

Density: 0.934 g/mL at 25 °C (lit.)

Chemical properties: It's a colorless flammable liquid with a sweet ether smell. It's miscible with ethanol, soluble in ether, acetone, chloroform, carbon tetrachloride and other organic solvents, and insoluble in water.

Uses of VAM

Vinyl acetate is the main raw material for the production of synthetic fiber vinylon. Self-polymerization of vinyl acetate or copolymerization with its monomers creates polyvinyl alcohol (PVA), vinyl acetate copolymer (EVA), vinyl chloride copolymer (EVC), vinyl acetate-acrylonitrile fiber, and vinyl acetate-acrylate copolymers, which have important industrial applications and are widely used as adhesives, architectural coatings, textile sizing agents and finishing agents, paper reinforcements and used for the manufacture of safety glass. Ethyl acetate reacted with ethanol and bromine produces bromoacetaldehyde diethyl acetal, which is the intermediate of the drug methimazole.

Invasive route of VAM

inhalation, ingestion, and percutaneous absorption.

Health hazards of VAM

This product is irritating to eyes, skin, mucous membranes and upper respiratory tract. Prolonged exposure creates an anesthetic effect, thus rapid withdraw from its leaking and contaminated areas to safe areas and isolation and strict access restriction are necessary. In addition, fire should be separated. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective fire protection clothing. Cut off sources of leakage as much as possible to prevent it floating into sewers, flood drains and other restricted spaces.

For a small amount of its leakage, vinyl acetate monomer can be absorbed with sand or other non-combustible materials. It can also be scrubbed with a non-combustible dispersant, which will be later diluted and poured into the waste water system.

For a large amount of its leakage, it can be dealt with by constructing embankments or digging pits for containment. The spray-like water is used to cool and dilute its vapor, protecting the on-site personnel and diluting the vapor into incombustibles. Use explosion-proof pump to transfer it to the tanker or special collector and have it recycled or transported to waste disposal sites for treatment.
