C12–C13 alcohol glycidyl ether

C12–C13 alcohol glycidyl ether is a mixture of organic chemicals in the glycidyl ether family. It is a mixture of mainly 12 and 13 carbon chain alcohols, also called fatty alcohols that have been glycidated. It is an industrial chemical used as a surfactant but primarily for epoxy resin viscosity reduction. It has the CAS number 120547-52-6.

Manufacture A fatty alcohol mixture rich in C12-C13 alcohols is placed in a reactor with a Lewis acid catalyst. Epichlorohydrin is then added slowly to control the exotherm. The reaction results in the formation of the halohydrins. This is followed by a caustic dehydrochlorination, to form C12–C13 alcohol glycidyl ether. The waste products are water, sodium chloride, and excess caustic soda. One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.

Uses As an epoxy modifier it is classed as an epoxy reactive diluent. It is one of a family of glycidyl ethers available used for viscosity reduction of epoxy resins. These are then further formulated into coatings, sealants, adhesives, and elastomers.Howarth G.A "Synthesis of a legislation compliant corrosion protection coating system based on urethane, oxazolidine and waterborne epoxy technology" pages 23,24,39 Master of Science Thesis April 1997 Imperial College London Resins with this diluent tend to show improved workability. It is also used to synthesize other molecules. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.

Toxicology The toxicology is fairly well known, and it is classed as a skin irritant.
