Barely carbonyl hydrogenation and the nuclear hydrogenation ketone - aldehyde resin and these manufacturing methods of the formaldehyde non- containing which designates alkyl aryl ketone and the formaldehyde which possess OH functionality as the base

摘要

This invention, barely OH functionality, barely ratio of crystallization possible chemical compound, barely viscosity, quite low color number and designates alkyl aryl ketone and the formaldehyde which quite possess high heat resistance and light resistance as the base, it regards the carbonyl hydrogenation and the nuclear hydrogenation ketone - aldehyde resin and the manufacturing method of formaldehyde non- containing.
