Propylene oxide is an acutely toxic and carcinogenic organic compound with the molecular formula CH3CHCH2O.
This colorless volatile liquid with an odor similar to ether, is produced on a large scale industrially.
Its major application is its use for the production of polyether polyols for use in making polyurethane plastics.
Propylene oxide is a chiral epoxide, although it is commonly used as a racemic mixture.
This compound is sometimes called 1,2-propylene oxide to distinguish it from its isomer 1,3-propylene oxide, better known as oxetane.
Production
Industrial production of propylene oxide starts from propylene.
Two general approaches are employed, one involving hydrochlorination and the other involving oxidation.
In 2005, about half of the world production was through chlorohydrin technology and one half via oxidation routes.
The latter approach is growing in importance.
The mixture of 1-chloro-2-propanol and 2-chloro-1-propanol is then dehydrochlorinated
Lime (calcium hydroxide) is often used to absorb the HCl.
Oxidation of propylene
The other general route to propylene oxide involves oxidation of propylene with an organic peroxide.
The reaction follows this stoichiometry:
CH3CH=CH2 + RO2H → CH3CHCH2O + ROH
The process is practiced with four hydroperoxides:
In the Halcon process, t-Butyl hydroperoxide derived from oxygenation of isobutane, which affords t-butanol.
This coproduct can be dehydrated to isobutene, converted to MTBE, an additive for gasoline.
Ethylbenzene hydroperoxide, derived from oxygenation of ethylbenzene, which affords 1-phenylethanol.
This coproduct can be dehydrated to give styrene, a useful monomer.
Cumene hydroperoxide derived from oxygenation of cumene (isopropylbenzene), which affords cumyl alcohol. Via dehydration and hydrogenation this coproduct can be recycled back to cumene.
This technology was commercialized by Sumitomo Chemical.
Hydrogen peroxide is the oxidant in the hydrogen peroxide to propylene oxide (HPPO) process, catalyzed by a titanium-doped silicalite:
C3H6 + H2O2 → C3H6O + H2O
In principle, this process produces only water was a side product. In practice, some ring-opened derivatives of PO are generated.

Production method
There are mainly chlorohydrin method and indirect oxidation.
1. Chlorohydrin method; apply propylene, chlorine and water for being acidified by hypochlorous at 60 °C under normal pressure to generate chloropropanol, followed by saponification, condensation and distillation to derive.
2. Indirect oxidation:
it is derived from the oxidation of ethylbenzene (or isobutane, cumene, etc.) to form hydrogen peroxide ethylbenzene (or tert-butyl hydroperoxide, cumene hydroperoxide, etc.), which further has epoxidation with propylene in the catalysis of naphthenic acid molybdenum.
(3) Electrochemical Chlorohydrin Method: this method is based on the principle that the aqueous solution of sodium chloride (or potassium chloride, sodium bromide, sodium iodide) for electrolysis to generate chlorine and sodium hydroxide.
Send the propylene in the anode area to generate chlorine alcohol, which further reacts with sodium hydroxide to generate propylene oxide in the cathode area.
The preparation method is as follows.
(1) Chlorohydrin method
Take propylene as raw materials, followed by hypochlorous acidification, saponification, and then enrichment and distillation to derive the products.
The reaction of propylene with hypochlorous acid is carried out in an aqueous solution, and the chlorine gas is mixed with hypochlorous acid and hydrochloric acid in water.
The reaction temperature is 30-50 DEG C, and the produced aqueous chloropropanol and 10% lime milk are saponified in a saponification reactor for saponification, the saponification kettle is sent into the water vapor, steaming out the propylene oxide, and then subject to condensed distillation derived products.
CH3CH = CH2 + HOCl →CH3CHOHCH2Cl + CH3CHClCH2OH
This method requires a low purity of propylene, and the yield is high, but it consuming large amounts of chlorine and lime milk, equipment with serious corrosion on the device, resulting in environmental pollution problems. Propylene oxide is mainly adopted in China to produce propylene oxide.
(2) Peroxide method
The main process is the manufacture of organic hydrogen peroxide.
Apply peroxide for oxidation of propylene.
This reaction is always liquid phase reaction either in the production of organic hydrogen peroxide or in the presence of a catalyst for the transfer of oxygen from the peroxide to the propylene molecule.
In addition to produce the propylene oxide as the main product, there are also co-products.
Current ways that has realized industrialization include ethyl benzene Haakon method and isobutane Haakon method.
Ethylbenzene Haakon mainly adopts ethylbenzene as raw material for production of ethylbenzene hydroperoxide by oxidation.
Under the catalyst of copper naphthenate, it is subject to propylene epoxidation reaction, generating propylene oxide as well as alpha-phenylethanol simultaneously, followed by dehydration to give the styrene.
The reaction temperature of ethylbenzene oxidation is 130-150 ℃, the pressure is 0.07-0.14 MPa, the selectivity of generating ethylbenzene hydroperoxide is 90%; the temperature of epoxidation is 50-120 ℃; The pressure is between atmospheric pressure to 0.864 MPa.
For example, a mixture of 14% of ethylbenzene hydroperoxide, 35% of propylene, 50% of ethylbenzene and 1% of α-phenylethanol is added to 0.4% of naphthenic acid manganese naphthenate (nMo/nNa = 2 , Molar ratio) to be as the catalyst for reaction at 1.5 h at 100 ℃, resulting conversion rate of ethylbenzene hydroperoxide, 99% and selectivity of propylene oxide as 78%.
The reaction product can be obtained by distillation of propylene oxide to obtain the finished product.
The α-phenylethanol, in the dehydration reactor, is subject to dehydration at 250-280 ℃ using TiO3-Al2O3 as catalyst, resulting a conversion rate to styrene of 100% with a selectivity of 92%.
The features of the method:
low cost, being economic and reasonable, less waste, with co-production of styrene.
Isobutane Haakon method uses isobutane as raw material, via oxidant tert-butyl hydroperoxide, further being reacted with propylene to generate propylene oxide and tert-butyl alcohol.
The whole process is similar to ethylbenzene Haakon method.
Manufacturing of tert-butyl hydroperoxide was carried out at 100~110 °C without catalyst, usually using tert-butyl hydroperoxide as initiator.
Epoxidation of propylene was carried out under the conditions of reaction temperature 121 °C and pressure of 4.1 MPa to be carried out in the presence of molybdenum catalyst.
The reaction time is 0.5 h with the yield of propylene oxide 88% (peroxides), selectivity of 81%.
