Product Application of 2-Ethylhexanoic acid CAS#149-57-5

Most of 2-ethylhexanoic acid is converted into salts of metal zirconium, cobalt, molybdenum, zinc, etc., which are used as paint driers and heat stabilizers for polyvinyl chloride plastics; tin salts are used as additives for plastic pipes; barium salts and cadmium salts are used for plastic calendering products and stabilizers. Chemicalbook2-ethylhexanoic acid and its esters are also used in medicine, fungicides, metal lubricants, cosmetics, etc. Its glyceride is an excellent plasticizer. 2-ethylhexanoic acid is the raw material of the pharmaceutical carbenicillin. It is also used in the synthesis of many dyes and fragrances.
