C12-C13 alcohol glycidyl ether is a mixture of organic chemicals in the glycidyl ether family. [1] It is a mixture of mainly 12 and 13 carbon chain alcohols, also called fatty alcohols that have been glycidated. [2] It is an industrial chemical used as a surfactant but primarily for epoxy resin viscosity reduction. [3] [4] It has the CAS number 120547-52-6. [5]
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. [6] This is followed by a caustic dehydrochlorination, to form C12-C13 alcohol glycidyl ether. [7] The waste products are water and sodium chloride and excess caustic soda. [8] One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.
The material has a number of synonyms. [9]
As an epoxy modifier it is classed as an epoxy reactive diluent. [10] It is one of a family of glycidyl ethers available used for viscosity reduction of epoxy resins. [11] [12] These are then further formulated into coatings, sealants, adhesives, and elastomers. [13] [14] Resins with this diluent tend to show improved workability. [15] It is also used to synthesize other molecules. [16] [17] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [18] [19]
The toxicology is fairly well known, and it is classed as a skin irritant. [20]
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. The IUPAC name for an epoxide group is an oxirane.
