Product parameters

English Alias	1,3-Butanediol (±)-1,3-Butanediol 1,3-Butylene glycol Butylene glycol +Expand -Stow	CAS NO	107-88-0
Molecule formula	C4H10O2	Molecular weight	90.121
Customs Code	2905399090

Nature Description

Colorless viscous liquid. Melting Point-77℃, boiling point ℃, relative density 1.0043(20/4 ℃), viscosity (25℃)103.9mPa · s, refractive index 1.4401, surface tension (25℃)37.8mN, m, flash point 121℃. Soluble in water, acetone, methyl ethyl (methyl) ketone, ethanol, dibutyl phthalate, castor oil, almost insoluble in aliphatic hydrocarbons, benzene, toluene, carbon tetrachloride, ethanol Amine, mineral oil, linseed oil. When hot, nylon can be dissolved, and shellac and turpentine can also be partially dissolved. Because the boiling point is relatively high, distillation under atmospheric pressure is easily subject to air oxidation, so it is appropriate to distillation under reduced pressure. Odorless, slightly bitter and sweet. Strong hygroscopicity, which can absorb water equivalent to 12.5 of its own weight (when the relative humidity is 50), even 38

Product Applications

Used as softening agent and organic synthesis; Carrier solvent (mainly used for curry); Spices.; 1, 3-butanediol has the characteristics of diol reaction, odorless, low toxicity, good water solubility and so on, and can be used in the following main aspects: 1.1,3-butanediol is used as the raw material of polyester resin and alkyd resin..

Production method

Acetaldehyde is used as raw material to generate 3-hydroxybutyraldehyde through self-condensation in alkali solution, and then hydrogenated to form 1,3-butanediol.
