Methyl Isobutyl Carbinol (MIBC)

CAS NO .: 108-11-2

Chemical properties of MIBC

Dethyl isobutyl carbinol (MIBC) is a colorless stable liquid. It has a melting point of -90°C, solidifying point of -90°C, boiling point of 132°C, relative density of 0.8083 (20/20°C), refractive index of 1.4112, flash point of 40.6°C, vapor pressure (20°C) of 0.373 kPa, and viscosity of 5.2 mPa·s. It will solidify to be a glass body below -90°C. Its steam with air forms an explosive mixture with an explosion limit of 1%-5.5%. It is miscible with various organic solvents and slightly soluble in water. Its soluble content in water at 20°C reaches up to 1.9%.

 

Applications of MIBC

4-Methyl-2-pentanol is an excellent medium boiling point solvent. MIBC solvent is mainly used as a solvent for dyes, petroleum, rubbers, resins, paraffin, nitrocellulose and ethyl cellulose, etc. It is used as an inert solvent for nitrocellulose lacquer, which can increase the gloss and flatness of the coating and improve the performance of reddening. It is used as a solvent in the manufacture of lubricating oil additives. It serves as a raw material for organic synthesis, and a mineral flotation agent like in extracting silicon and copper sulfate ore; It can also be used in brake fluid.

 

It can be used as a foaming agent, dispersant, detergent, plasticizer, surfactant, or lubricant and in the manufacture of cosmetics and pharmaceuticals in the photographic industry.

Ethyl Methacrylate(EMA)

CAS NO .: 97-63-2

 Properties: Ethyl methacrylate (EMA) is a colorless liquid and easy to volatilize with a spicy smell.

 Melting point (°C): -75

 Boiling point (°C): 117~119

 

Uses of EMA

EMA monomer is a commonly used polymerizable monomer and can be used as an intermediate for adhesives, coatings, fiber treatment agents, molding materials, and also for the manufacture of acrylic copolymers. It can be copolymerized with methyl methacrylate to improve its brittleness. It can also be used to make organic glass, synthetic resin, and molding powder.

 EMA is used for preparing polymers, copolymers, synthetic resins, organic glass and coatings.

 

Storage of EMA

EMA liquid is a colorless liquid and easy to volatilize with a spicy smell. It is slightly soluble in water and miscible in alcohol and ether. It should be stored in cool and ventilated warehouses, and be kept away from fire, heat sources, and light. The temperature in warehouses should not exceed 37°C. It should be sealed in packaging and must not come into contact with air.

 

At room temperature, EMA is a colorless liquid and easy to volatilize with a spicy smell. It is slightly soluble in water and miscible in alcohol and ether. It is stored and easily deteriorated due to polymerization, and it is necessary to add a polymerization inhibitor. It is highly flammable and its vapor can form an explosive mixture with air. It is a toxic chemical harmful to human body when inhaled, orally taken or absorbed through the skin. Its vapor or smoke is irritating to the eyes, skin, mucous membranes, and upper respiratory tract. Its poisoning symptoms include a burning sensation, cough, wheezing, shortness of breath, laryngitis, headache, nausea, vomiting, and allergic reactions. It can be used as an intermediate for adhesives, coatings, fiber treatment agents, and molding materials.

 

R11: EMA is highly flammable.

R36/37/38: EMA is irritating to eyes, respiratory system and skin.

R43: EMA may cause sensitization by skin contact.

S16: EMA should be kept away from sources of ignition.

S29: Do not empty EMA into drains.

S33: Take precautionary measures against static discharges. Take measures to prevent static electricity from occurring.

S9: Keep the storage container in a well-ventilated place.

 

Explosive hazardous characteristics

When mixed with air, EMA can explode.

Flammability hazard characteristics

In case of fire, high temperature, or oxidant, EMA is likely to fame; Its burning produces irritating smoke.

 

Storage and transportation characteristics of EMA

The warehouse should be ventilated and kept dry at low temperatures; It should be stored separately from oxidants and acids; It should not be stored for a long time in case of polymerization.

 

Extinguishing agents

Dry powder, dry sand, carbon dioxide, foam, and 1211 fire extinguishing agent.
