  • Propylene oxide is a volatile, clear, colorless, extremely flammable liquid with an ether-like odor.
  • Propylene oxide is a highly toxic flammable chemical compound. It is an epoxide having a molecular formula C3H6O.
  • Propylene oxide is obtained through propylene hydro chlorination. It is soluble in water and miscible with acetone, benzene, carbon tetrachloride, diethyl ether, and ethanol.
  • Propylene oxide (PPO) is a liquid fumigant under normal temperature pressure (NTP) with a low boiling point (35°C) and a noticeable ether odour.
  • Propylene Oxide is produced via the established chlorohydrin process, in which propylene and chlorine react in the presence of water to form the intermediate propylene chlorohydrin.
  • The hydroperoxide process is another costly method for producing propylene oxide (PO). This process uses ethylbenzene with oxygen to produce an organic-hydroperoxide.
  • The hydroperoxide is used to oxidize propylene to PO, which is then purified. This process results in a large quantity of by-product, phenylmethylcarbinol, which is dehydrated to styrene, another useful chemical.
  • At present there are two major industrial processes used for the synthesis of propylene oxide: The chlorohydrin and peroxide processes.
  • The new propylene oxide cumene process is considered as one of the Green Processes since it gives higher yields then the conventional processes with only small amont of by products produced.
  • In previous year, about half of the world production was through chlorohydrin technology, one third from PO/SM technology, and the other from PO/TBA technology. The above technologies create additional side products.
  • Propylene oxide is also used in the production of propylene glycol, polypropylene glycol, propylene glycols ethers and propylene carbonate.
  • Its major industrial application is as a monomer for the production of polyether polyols for use in making polyurethane plastics.
  • Propylene oxide may be used in fumigation chambers for the sterilization of packaged foods and as a pesticide.
  • Propylene oxide is a key raw material for various kinds of products such as polypropylene glycol, propylene glycol, and surfactants, which have a broad range of applications including polyurethane foams, elastomers, paints, adhesives, and unsaturated polyesters.
  • Propylene oxide is used primarily as a building block for the manufacture of a versatile range of derivative products.
  • Propylene oxide (Po) is normally used in the gaseous form to prevent microbial spoilage in food products.
  • Propylene oxide (PPO) is a registered fumigant in the US for reduction of bacteria, yeasts, and mold on raw nut meats, etc., and PPO fumigation has been used by the nut industry for insect and microbial control for decades.
  • The total production capacity of propylene oxide in Japan is approximately 350 thousand tons at present, including the 170 thousand tons of Nihon Oxirane.
  • There are a number of known technologies to produce propylene oxide but Shell chemicals companies and their joint ventures employ the Shell proprietary SM/PO technology.
  • During the past 10 years, propylene oxide grew at a nearly 4 percent annual rate. Propylene oxides's growth should moderate to about 3 percent in the present decade because most of its applications are maturing.
  • Commercial production is from propylene and chlorine in a chlorohydrin process, or from peroxidation of propylene and another petrochemical reactant that results in PO plus an additional co-product.
  • Propylene oxide is a major industrial product with production of more than 6 million tons per year world wide. Approximately 70% of it is used as polypropylene glycol in the raw materials for urethane, and the remainder is used as propylene glycol in the raw materials for unsaturated polyesters, food product additives and cosmetics.
