High quality Trimethylolpropane(TMP) CAS:77-99-6
The chemical name of trimethylolpropane (TMP) is 2-ethyl-2-hydroxymethyl-1,3-propanediol, also known as trimethylolpropane and 2,2-dimethylolbutanol. 3 typical methylol groups, which have the properties of polyols similar to glycerol, can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanate Chemicalbook esters It is a kind of chemical raw materials and chemical products with a wide range of uses. It is mainly used in the fields of alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings, etc., and can also be used to synthesize aviation lubricants and plasticizing. Agents, surfactants, wetting agents, explosives, printing inks, etc., can also be used directly as textile auxiliaries and heat stabilizers for PVC resins.
Trimethylolpropane is a Colorless, hygroscopic crystals. Soluble in water and alcohol. Combustible.The three primary hydroxyl groups undergo the normal OH group reactions.
- Synthetic alkyd resin
Because the trimethylolpropane molecule contains a special molecular structure with three primary hydroxyl groups, it can not only replace glycerin to synthesize alkyd resin, but also replace or share with polyols such as neopentyl glycol and pentaerythritol to produce alkyd resin. Compared with alkyd resins made with polyols such as glycerin, neopentyl glycol, and pentaerythritol, it has better hydrolysis resistance, oxidation stability, alkali resistance and thermal stability, and also has bright color and color retention. It has the advantages of strong strength, temperature resistance and quick-drying. It is especially suitable for the production of road marking paints and varnishes. It can also be used as a top coat for automobiles, refrigerators, washing machines, bicycles, aviation and navigation. Alkyd resin synthesized from trimethylolpropane has good compatibility with amino resin, and can be used as raw material for polyurethane coatings, and can also be used as high-grade coatings such as urethane self-drying paint and baking paint.
- Synthetic premium lubricants
The esters of trimethylolpropane can be used to synthesize advanced lubricating oil. The lubricating oil synthesized from trimethylolpropane has the advantages of low melting point, high viscosity, high ignition point, and strong oxidation resistance. It is widely used in the lubrication of aircraft engines and can be used at temperatures above 200°C. It can also be used in automobile engines. The performance of air compressor and refrigerator lubrication is better than that of lubricating oil synthesized from neopentyl glycol. In addition, synthetic oil mainly made of trimethylolpropane can also be used in the processing of bearing steel.
- Production of polyester and polyurethane foam
Trimethylolpropane is widely used in the production of polyurethane elastomers and polyurethane foams. The carbamate produced by trimethylolpropane, toluene diisocyanate (TDI), and 1,3-butanediol has the advantages of high hardness, good elasticity, wear resistance and aging resistance, and is widely used in solid tires, Conveyor belts, sponge manufacturing, thermal processing and aerospace industries; polyether polyols with free hydroxyl groups produced by the reaction of trimethylolpropane with ethylene oxide or propylene oxide are the main raw materials for the production of flexible polyurethane foams , Synthetic polyurethane has the dual properties of rubber and plastic. It has the characteristics of high elasticity, wear resistance, washing resistance, durability, fluorescence, and bright colors. It is especially suitable for the production of road sign paint, varnish, electrophoretic paint, etc., and can also be used for manufacturing Seat cushions, backrests, steering wheels, instruments, armrests, bumpers for airplanes, automobiles, trains, and tires, used in shoe soles, solid tires, conveyor belts, sponges, aerospace, thermal processing, and building materials; trimethylolpropane and glycerin Maleic acid-synthesized polyester has the characteristics of weather resistance, radiation resistance, flexibility and reduction of polyester self-dyeing properties, and is widely used as a substitute for building materials and leather industry. In the production of foam, trimethylolpropane can also partially or completely replace 1,4-butanediol.
- Preparation of plasticizer
In the presence of non-acidic catalysts, trimethylolpropane reacts with monobasic aromatic acids and C5-C9 fatty acids to generate composite esters. It is a kind of plasticizer with good performance. The polymer added to the ester has good high temperature resistance, Hydrolysis resistance, acid and alkali resistance, and good affinity with polyvinyl chloride (PVC). PVC plastics containing this plasticizer can still maintain good electrical insulation in the presence of water in Chemicalbook. In addition, trimethylolpropane can also replace isodecyl alcohol in the production of important advanced plasticizer diisodecyl phthalate, which is used in the production of special coatings such as cables.
- Preparation of emulsifier
Trimethylolpropane is partially esterified with monobasic fatty acids and then reacted with ethylene oxide to produce semi-solid compounds. It has a good emulsification effect on oil/water emulsions and can be used as an emulsifier for medicines and cosmetics. The nonionic surfactant prepared by the addition of trimethylolpropane and propylene oxide has excellent emulsification and wettability. The alkyd resin made of trimethylolpropane and high molecular weight dibasic fatty acid containing two double bonds is a water/oil type emulsifier, which has a wide range of applications in the textile and printing and dyeing industries.
- Preparation of liquid fuel additives
Trimethylolpropane is esterified with oleic acid and then reacted with polyformaldehyde to prepare a liquid fuel additive. The liquid fuel after adding 0.5% to 1% of this substance can purify the exhaust gas without a vaporization device.
- Production of trimethylolpropane triacrylate (TMPTA)
Trimethylolpropane triacrylate (TMPTA) obtained by the reaction of trimethylolpropane and acrylate is the most widely used multifunctional acrylate reactive diluent in the field of radiation curing. It has high double bond content, fast curing, Wear resistance, solvent resistance and other properties, mainly used as a reactive diluent for UV-curable coatings and inks. It dilutes before UV irradiation, and after irradiation, it also reacts to form part of the cured film. TMPTA can also be used to prepare unsaturated polyester glass fiber reinforced plastics, reinforced plastics, special alkyd resins, adhesives, synthetic oils, rosin ester explosives, synthetic fiber additives, and for the processing of chemical membranes.
- Production of trimethylolpropane trimethacrylate (TMPTM)
Trimethylolpropane trimethacrylate (TMPTM) obtained by the esterification reaction of trimethylolpropane and methacrylic acid is a multifunctional monomer, which can be used for the shaping of PVC latex (anti-corrosion rubber shoes, etc.) and cross-linked PVC The coated wire can also be used as an anaerobic adhesive, rubber (ethylene propylene rubber) cross-linking agent and ink curing agent, and can also be used to modify coatings and resins.
- Production of trimethylolpropane triglycidyl ester (TMPTE)
Trimethylolpropane triglycidyl ester (TMPTE) prepared by the reaction of trimethylolpropane and epichlorohydrin can be used as a reactive diluent for epoxy resin (epoxy resin coating), polyester and melamine resin, etc. Modifiers, fiber processing agents (anti-wrinkle treatment agents) and adhesion modifiers.
- Other aspects
Trimethylolpropane and phosphoric acid undergo heating reaction, vacuum dehydration, and then add excess epichlorohydrin for polycondensation reaction.
