DEFINITION

Classification: 568/886

Preparing by alcoholysis, hydrolysis, or saponification of ester of polybasic inorganic acid:

(under subclass 840) Processes which include treating an ester of a polybasic inorganic acid with a compound which contains -OH (e.g., alcohol, water, NaOH, etc.)to form the compound.

(1) Note. This subclass provides for processes wherein an olefin is first converted into an alkyl ester and subsequently subjected to hydrolysis.

SEE OR SEARCH THIS CLASS, SUBCLASS:

895+, for processes wherein olefins are hydrated with water, for example, steam, in the presence of a polybasic inorganic acid.
