C12-C14 alcohol glycidyl ether (AGE) is an organic chemical in the glycidyl ether family.[2] It is a mixture of mainly 12 and 14 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.[3] It has the CAS number 68609-97-2 but the IUPAC name is more complex as it is a mixture and is 2-(dodecoxymethyl)oxirane;2-(tetradecoxymethyl)oxirane;2-(tridecoxymethyl)oxirane.[4] Other names include dodecyl and tetradecyl glycidyl ethers and alkyl (C12-C14) glycidyl ether.

Manufacture

[edit]

A fatty alcohol mixture rich in C12-C14 alcohols is placed in a reactor with a Lewis acid catalyst. Then epichlorohydrin is added slowly to control exotherm which results in the formation of the halohydrins.[5] This is followed by a caustic dehydrochlorination, to form C12-C14 alcohol glycidyl ether.[6] The waste products are water and sodium chloride and excess caustic soda.[7] One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.

Uses

[edit]

As an epoxy modifier it is classed as an epoxy reactive diluent.[8] It is one of a family of glycidyl ethers available used for viscosity reduction of epoxy resins.[9] These are then further formulated into coatings, sealants, adhesives, and elastomers.[10][11] Resins with this diluent tend to show improved workability.[12] It is also used to synthesize other molecules.[13][14] The use of the diluent does effect mechanical properties and microstructure of epoxy resins.[15][16]

Toxicology

[edit]

The toxicology is well known, and it is classed as a skin irritant.[17]
