Chemical properties: 1,2-pentanediol is a colorless transparent liquid, b.p.206 ℃, n20D 1.4400, the relative density of 0.971, soluble in alcohol, ether and ethyl acetate and other organic solvents.

Usage:

1.1,2-pentanediol is an important intermediate for the fungicide azoxazole.
2.excellent performance of the humectant, at the same time with anti-corrosion effect, can be formulated without preservatives products to reduce the allergies caused by preservatives;
3. can improve the sunscreen product formula of water resistance;
4.dissolve insoluble active ingredients. For skin care cream, eye cream, skin care, baby care products, sunscreen products and other skin care products.

Brief manufacture process:
The preparation method is 1-pentene, hydrogen peroxide and formic acid as raw materials, the molar ratio of 1: 1.5: 4. The reaction equilibrium mixture was formed by slowly adding 1-pentene and hydrogen peroxide (70%) simultaneously to formic acid at 40 to 55 ° C. After the addition was complete, the mixture was stirred at 55 ° C for 1 h, Into the circulation reactor, which has a circulating pump and an overflow siphon, heated to 55 ° C and circulated, followed by the addition of 1-pentene and formic acid, added by an addition tube, and hydrogen peroxide being fed from another addition tube. When the exothermic reaction occurs, the temperature allowed to rise to 62 ~ 63 ℃, according to a certain proportion and speed to join these components, the balance operation to cycle thermostat device control, for about 8h, the reaction stopped to get a lot of 1,2-pentanediol The resulting residue was distilled to remove formic acid and water. The resulting residue was hydrolyzed by the addition of 25% NaOH solution and the solvent was removed by solvent extraction to give 1,2-pentanediol in a yield of 91%, m p. 96 to 98 ° C / 1.3 kPa.
