Process for the preparation of an alkyl methacrylate

A two-step reaction process for converting ethylene oxide with high selectivity into monoethylene glycol which comprises firstly reacting ethylene oxide with acetone in the presence of a solid acid catalyst to form 2,2-dimethyl-1,3-dioxolane and secondly hydrolyzing the 2,2-dimethyl-1,3-dioxolane with water in the presence of a solid acid catalyst to form monoethylene glycol.

Two-step monoethylene glycol preparation process

Process for preparing adipic acid or esters thereof by:

Process for the preparation of a diester of adipic acid

The invention relates to polyglycidyl ethers and provides such compounds based on diphenylol C.sub.7 to C.sub.13 alkanes, and their preparation from the appropriate diphenylol alkanes. The polyglycidyl ethers may be cured with known epoxy resin curing agents and may be used as base materials for the preparation of anionic or cationic aqueous thermosetting paint binders. The polyglycidyl ethers exhibit good compatibility with aliphatic hydrocarbon solvents.

Polyglycidyl ethers, their preparation and use in curable compositions

Diglycidyl ethers are prepared from a mixture of isomers of 1,1-bis(hydroxyphenyl)heptane. The diglycidyl ethers have low viscosity and good compatibility with aliphatic hydrocarbon solvents; they can be cured with the usual curing agents for epoxy resins, e.g., polyamines, and can be used in solventless coating compositions.
