Abstract
A process for making a phenolic ketone involving reacting a metal aryloxide with an aliphatic aldehyde having from at least 2 to about 25 carbon atoms.
Claims21
A process for making phenolic ketones corresponding to formula I:
- ##STR7## wherein R.sub.1 is a C.sub.1 to C.sub.24 alkyl group, X is a hydrogen or halogen atom, or an alkyl, cycloalkyl, aralkyl, aryl, alkaryl, alkoxy, aryloxy, acyl or hydroxy group, n is an integer from 1 to 4, and R.sub.1 and X have a combined total of from about 3 to about 25 carbon atoms comprising:
- (a) providing a metal aryloxide wherein the metal is a metal selected from the group consisting of metals from Groups IA, IIA, IIIA, and IVB of the periodic table;
- (b) providing an aliphatic aldehyde having from at least 2 to about 25 carbon atoms;
- and
- (c) reacting the metal aryloxide with the aliphatic aldehyde to form a phenolic ketone, wherein step (c) is carried out at a temperature of from about 20 to about 250.degree. C. and at a pressure of from atmospheric to about 300 psi.

A process for making a phenolic ketoxime corresponding to formula II:
- ##STR9## wherein R.sub.1 is a C.sub.1 to C.sub.24 alkyl group, X is a hydrogen or halogen atom, or an alkyl, cycloalkyl, aralkyl, aryl, alkaryl, alkoxy, aryloxy, acyl, hydroximinoacyl or hydroxyl group, n is an integer from 1 to 4, and R.sub.1 and X have a combined total of from about 3 to about 25 carbon atoms, comprising:
- (a) providing a metal aryloxide;
- (b) providing an aliphatic aldehyde;
- (c) reacting the metal aryloxide with the aliphatic aldehyde to form a phenolic ketone;
- (d) providing a source of hydroxylamine;
- and
- (e) reacting the phenolic ketone with the hydroxylamine to form the phenolic ketoxime;
- wherein step (c) is carried out at a temperature of from about 20 to about 250.degree. C. and at a pressure of from atmospheric to about 300 psi, step (e) is carried out at a temperature of from about 20 to about 100.degree. C., and the metal in the metal aryloxide in (a) is a metal selected from the group consisting of metals from Groups IA, IIA, IIIA, and IVB of the periodic table.
