Ethylene oxide is a colorless gas at 25 °C (77 °F) and is a mobile liquid at 0 °C (32 °F) – viscosity of liquid ethylene oxide at 0 °C is about 5.5 times lower than that of water. The gas has a characteristic sweet odor of ether, noticeable when its concentration in air exceeds 500 ppm. Ethylene oxide is readily … See more Ethylene oxide is an organic compound with the formula C2H4O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and See more The epoxy cycle of ethylene oxide is an almost regular triangle with bond angles of about 60° and a significant angular strain corresponding to … See more Ethylene oxide readily reacts with diverse compounds with opening of the ring. Its typical reactions are with nucleophiles which proceed via the SN2 mechanism both in acidic (weak nucleophiles: water, alcohols) and alkaline media (strong nucleophiles: OH , … See more History Commercial production of ethylene oxide dates back to 1914 when BASF built the first factory which used the chlorohydrin process (reaction of ethylene chlorohydrin with calcium hydroxide). The chlorohydrin process was … See more Ethylene oxide was first reported in 1859 by the French chemist Charles-Adolphe Wurtz, who prepared it by treating 2-chloroethanol with potassium hydroxide: Wurtz measured the See more Dehydrochlorination of ethylene and its derivatives Dehydrochlorination of 2-chloroethanol, developed by Wurtz in 1859, remains a common laboratory … See more Ethylene oxide is one of the most important raw materials used in large-scale chemical production. Most ethylene oxide is used for … See more WebFor example, with alcohol ethoxylates, the HLB value is directly proportional to the surfactant’s ethylene oxide (EO) chain length. More specifically, a linear alcohol ethoxylate with 8 moles EO will have a higher HLB value, and better water solubility, than a linear alcohol ethoxylate with 3 moles EO. Calculating HLB values of Nonionic ...
