Oxyde d'éthylèneL'oxyde d'éthylène, ou 1,2-époxyéthane, oxyde de diméthylène, oxacyclopropane, ou encore oxirane est un composé organique, le plus simple de la classe des époxydes. Il est important pour l'industrie chimique, entre autres dans la production d'éthylène glycol, ainsi que dans les industries pharmaceutique et agroalimentaire.

| Résumé : |
Epoxidized fatty esters derived from natural oils and synthetic oils find widespread applications and principally as secondary plasticizers for polyvinyl chloride (PVC) and copolymers. A number of vegetable oils such as linseed, safflower, corn, cotton seed, rapeseed, peanut have been expoxidized to yield commercially acceptable plasticizers and other additives. On account of production volume, availability and favourable economics, soybean oil is gaining preferance worlwide for the manufacture of epoxidized vegetable oil plasticizers. In the present study, soibean oil has been epoxidized for varying durations using different concentration of acidic catalysts viz. sulfuric acid, ortho phosphoric acid and Amerlite IR 120 and per acid formed in-situ. The prepared epoxidized soybean oil was characterized for various physico-chemical properties, viz. refractive index, iodine value, oxirane content etc. The results revealed the activity of catalysts in order of ortho-phosphoric acid |
