It is an important raw material for organic synthesis. Used for lubricant synthesis, surfactant, detergent, and insecticide manufacturing.
There are mainly chlorohydrin method and indirect oxidation method. 1. The chlorohydrin method is made from propylene, chlorine and water by hypochlorous acidification at atmospheric pressure and 60℃, and then by saponification, condensation and distillation. 2. Indirect oxidation method is made of ethylbenzene hydroperoxide (or tert-butyl hydroperoxide, isobutane, cumene, etc.) by oxidation. In the presence of catalysts such as molybdenum naphthenic acid, it is obtained by epoxidation with propylene. 3. Electrochemical chlorohydrin method this method uses aqueous solution of sodium chloride (or potassium chloride, sodium bromide, sodium iodide) to generate chlorine and sodium hydroxide through electrolysis. Propylene is introduced at anodic area to generate chloropropyl alcohol, in the cathode region, chloropropyl alcohol interacts with sodium hydroxide to generate propylene oxide.
S45: If you have an accident or feel uncomfortable, go to the doctor for help immediately (it is better to bring the product container label).
S53: Avoid exposure-read the special instructions before using.
R12: extremely flammable. R45: may cause cancer. R46: it may cause genetic damage. R20/21/22: inhalation, skin contact and accidental swallowing are harmful. R36/37/38: it can irritate eyes, respiratory tract and skin.

In the first half of 2022, the market price of propylene oxide PO rose and fell frequently, and the profit of chlorohydrin process dropped by more than 90% year on year.
Epoxy resin, bisphenol A and other raw materials continue to be in a weak situation of supply and demand; Foreign giants issued an early warning of "off supply" of chemical raw materials
What are the role and uses of propylene oxide
PO capacity expansion, Qixiang Tengda 300000 tons/year propylene oxide project put into operation
PO added new production capacity, Taixing 150000 tons/year PO project passed the completion acceptance.
Propylene oxide production process competitiveness analysis, which process is better?
270000 tons of propylene oxide, 600000 tons of styrene started; propylene oxide and styrene market analysis
China Chemical Tianchen 600000 Tons/Year Propylene Oxide Full-scale
