The ketoxime ester compound has a specific structure and the photopolymerization composition contains the ketoxime ester compound.

The invention relates to a process for the separation of a ketoxime or aldoxime from a ketoxime- or aldoxime-containing amide mixture in which the ketoxime or aldoxime is separated from the amide mixture by means of distillation.

Disclosed are certain ketoxime-blocked polyisocyanates and polyester compositions containing the ketoxime-blocked polyisocyanates.

Ketoxime carbonates are useful in a variety of applications.

The first step, Step (A), involves forming a ketoxime.

The extractant is preferably an oxime extractant, either a ketoxime or an aldoxime.

Extractant compositions comprising a ketoxime and modifier are also provided.

The oxime-based extractant is preferably ketoxime-based.

A composition includes an elastomer and a ketoximo silane or a ketoxime additive.

The ketoxime ester photoinitiator solves the problems that the existing ketoxime ester photoinitiator such as OXE-1 has bad application performance and bad thermal stability.

The invention relates to novel ketoxime carbonates and a process for the synthesis of ketoxime carbonates generally.

The second step, Step (B), involves adding an alkylating agent to the ketoxime formed in Step (A).

Additionally, the antifouling coating composition can comprise an acetoxy, alkoxy, and/or ketoxime functional adhesion promoter.

In particular, provided are reagent compositions comprising an aldoxime and ketoxime with an alkyl substituent.

This has proved to be a very simple and direct method for separating the ketoxime and/or aldoxime from the desired amide.
