| Usage: | Trimethylolpropane is an important fine chemical product and a commonly used chain extender in the resin industry. Its melting point is low, and there are three hydroxymethyl groups in its molecular structure. It can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanates to form amino esters. The product is mainly used in the fields of alkyd resin, polyurethane, unsaturated resin, polyester resin, coatings, etc. It can also be used for synthesizing aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, etc. It can also be used as a textile additive and thermal stabilizer for polyvinyl chloride resin. Emergency Management Isolate the contaminated area and restrict access. Cut off the fire source. It is recommended that emergency personnel wear dust masks (full face shields) and general work clothes. Mix with sand, dry lime, or soda ash. Collect in a dry, clean, and covered container and transfer to a safe location. If there is a large amount of leakage, collect and recycle it or transport it to a waste disposal site for disposal. Storage and transportation characteristics 1. Precautions for operation. Sealed operation, strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid contact with oxidants and acids. Handle with care during transportation to prevent packaging damage. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances. 2. Storage precautions. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from oxidants and acids, and avoid mixing storage. Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials. When shipping, the packaging should be intact and the loading should be secure. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with oxidants, acids, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures. | |
| Description: | (hydroxymethyl)propane-1,3-diol Physical and chemical properties Appearance: White flaky crystals. Density: 1.116g/ml Melting point: 56-60 ℃ Boiling point: 295.7 ℃ (760 mmHg) Flash point: 172 ℃ Solubility: Easily soluble in water, low-carbon alcohols, glycerol, N, N-dimethylformamide, partially soluble in acetone and ethyl acetate, slightly soluble in carbon tetrachloride, ether, and chloroform, insoluble in fatty hydrocarbons, aromatic hydrocarbons, and chlorinated hydrocarbons. Its hygroscopicity is about 50% that of glycerol. synthetic method Butyraldehyde and formaldehyde undergo condensation reaction under alkaline conditions. The reaction solution is concentrated and desalted, then decolorized and purified using ion exchange resin. Finally, it is evaporated, cooled, and rolled using a thin film evaporator to obtain the finished product. | |
