Description of Methyltrimethylene
- 1,3-Butanediol (also known as 1,3-butylene glycol, butane-1,3-diol, or 1,3-dihydroxybutane) is an organic chemical, an alcohol. It is commonly used as a solvent for food flavouring agents and is a co-monomer used in certain polyurethane and polyester resins. It is one of four stable structural isomers of butanediol. In biology, 1,3-butanediol is used as a hypoglycaemic agent. 1,3-Butanediol can be converted into β-hydroxybutyrate and serve as a substrate for brain metabolism.

What is 1,3-Butanediol?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Methyltrimethylene which has developed particularly rapidly in recent years. Do you know about Methyltrimethylene?
- The official answer：Clear, colorless, hygroscopic, viscous liquid with a weak special taste. Almost odorless. Boiling point 207.5℃, relative density (4:1.0059, refractive index (nD20) 1.4401, freezing point <-50℃, flash point 121.1℃. It has some antibacterial effects. Miscible in water, acetone, soluble in ether.c
What’s the application of 1,3-Butanediol?
- Methyltrimethylene has the characteristics of diol reactivity, odorless, low toxicity, good water solubility, etc. It can be used in the following main areas: 1. as a raw material for polyester esters, alkyd resins unsaturated polyester made from Methyltrimethylene or ethylene glycol mixed with good water resistance, softness, and impact resistance. 2. as a raw material for plasticizers polyester system made from Methyltrimethylene and diacid (adipic acid) Plasticizer with low volatility, migration resistance, soap and water resistance, solvent resistance, and oil resistance.3. Used as raw material for polyurethane coating as raw material for saturated polyester for polyurethane coating, the resulting product can get good water resistance in the uncoated paint, better than the effect of using other diols.4. Used as a wetting agent and softenerMethyltrimethylene has excellent moisturizing property and low toxicity, after making ester, it can be used as Methyltrimethylene is used as a wetting and softening agent for cigarette, celluloid, vinyl film, paper, fiber, etc. 5. Used as a solvent for fine chemicals, it can be used in the formulation of make-up, cream, cream, toothpaste, etc. Methyltrimethylene is also an intermediate for medicine and dyestuff. Manufacture polyurethane. Surfactants, plasticizers, coupling agents, solvents, food additives, and flavors. UsesMethyltrimethylene has the characteristics of reactivity of diol, odorless, low toxicity, good water solubility, etc. It is mainly used in organic synthesis and is the raw material of polyester tree ester and alkyd resin, the raw material of plasticizer, the raw material of polyurethane coating, wetting agent and softener, intermediate of medicine, and dyestuff.
