- 摘要：
- Antifoam compositions on the basis of an alpha -hydroxyamine derivative of the formula <IMAGE> wherein A is -NHCO- or -NHCONH-, R1 and R2 are H or alkyl having 1 to 22 carbon atoms and the sum of the carbon atoms in R1 and R2 is from 8 to 22, and R3 is alkyl having 8 to 22 carbon atoms or hydroxyalkyl having 8 to 22 carbon atoms; as well as the process of controlling foam in a foamable liquid by introducing therein an antifoam effective amount of said alpha -hydroxyamine derivative. The antifoam alpha -hydroxyamine derivatives are effective antifoam agents for most industrial purposes and are suitable for use in oil and latex paints.
