introduction	polypropylene glycol is a polymer with the molecular formula H(C3H6O)nOH, a colorless to light yellow viscous liquid. Not volatile. Non-corrosive. The molecular weight of general commodities is 400~2050. Lower molecular weight polymers are soluble in water. Higher molecular weight polymers are only slightly soluble in water, soluble in oils, many hydrocarbons, aliphatic alcohols, ketones, esters, etc. The hydroxyl groups at both ends of the molecule can be esterified to form monoesters or diesters. Its monoester is a non-ionic surfactant, and can also react with alcohol to form ether. It is a solvent for vegetable oil, resin and paraffin, and is also used to prepare alkyd resin, emulsifier, demulsifier, lubricating oil and plasticizer. It is obtained by condensation of propylene oxide and propylene glycol under high pressure or in the presence of an acidic catalyst.
use limit	for fermentation process, limited to GMP (GB 2760-96).
toxicity	LD50>10 g/kg (mouse, oral). mutagenicity test, Ames test, mouse bone marrow micronucleus test, mouse sperm aberration test, no abnormalities. Propylene glycol stimulation of rabbit corneal epithelium will produce temporary slight corneal congestion. If propylene glycol is washed with 50% aqueous solution for 5 minutes to remove propylene glycol, it will not cause any harm, but if it is stimulated with undiluted propylene glycol for 5 minutes, it will produce moderate reaction.
emergency operation	treatment method after contact: 1. inhalation: move to fresh air and rest. 2. Skin contact: remove contaminated clothes and rinse skin or shower with plenty of water. 3. eye contact: open your eyes, rinse with flowing water for 10 minutes, and then see a doctor.
use	defoamer; Solvents for vegetable oil, wax and resin. Used for eucalyptus sugar, beverages, candy, yeast, etc. Defoamer. Used in the production of yeast, monosodium glutamate, etc. The defoaming efficiency is several to dozens of times that of edible oil.
production method	glycerin and refined propylene oxide are polymerized under the catalysis of potassium hydroxide at a temperature of 90~95 ℃ and a pressure of 0.4 ~ 0.5MPa. Then cool to 60~70 ℃, press the material into a neutralization kettle, add water under stirring to neutralize excess potassium hydroxide, then add phosphoric acid at 60~70 ℃ to neutralize to pH 6~7, then slowly raise the temperature to 110~120 ℃, dehydrate and filter in vacuum. It is formed by the addition reaction of propylene glycol polymer and water.
