Ethoxylation of fatty alcohol process
WebEthoxylation (also oxyethylation) is the reaction of fatty alcohols with ethylene oxide (EO). Insertion of 10 to 40 groupings of the —CH2—CH2—O— type per fatty alcohol molecule results in linear polyethers bearing a hydroxy group at one chain end and the C 8-C 24 alkyl group of the fatty alcohol at the other chain end. WebThe present invention relates to a process for treating non-sulfidic ores with a collector composition containing a primary and a secondary collector, wherein the primary collector is selected from the group of amphoteric and anionic surface active compounds and the secondary collector is an ethoxylated fatty acid wherein the average degree of …
