You won't believe these 10 facts about people. Ethoxylation is a chemical process used in industry to create surfactants, which are compounds that reduce the surface tension of liquids. The process of ethoxylation involves adding ethylene oxide to an alcohol or phenol to produce products.
Selective alkylation, or adding parts to the chain with the desired functional groups, is used, especially if there is no commonly available biological precursor. Alkylation with only one carbon is termed methylation. In oil refining contexts, alkylation refers to a particular alkylation of isobutane with olefins. For upgrading of petroleum, alkylation produces synthetic C7âC8 alkylate, which is a premium blending stock for gasoline. In medicine, alkylation of DNA is used in chemotherapy to damage the DNA of cancer cells. Alkylation is accomplished with the class of drugs called alkylating antineoplastic agents.
