APPLICATIONS
2-Ethyl-2-butyl-1,3-propanediol is an aliphatic diol (two primary hydroxyl groups at 1,3-position) with two aliphatic branches. It is used in the production of polyesters, polyurethane coatings, adhesives, sealants or elastomers. It is also used as an intermediate for synthetic lubricants, plasticizers, photographic materials, pharmaceuticals, pesticides, fragrances, fibre lubricants antistatic agents and fabric softeners.

GENERAL DESCRIPTION OF 1,3-PROPANEDIOL
Glycol: any of a class of organic chemicals characterized by having separate two hydroxyl (-OH) groups, contribute to high water solubility, hygroscopicity and reactivity with many organic compounds, on usually linear and aliphatic carbon chain. The general formula is CnH2n(OH)2 or (CH2)n(OH)2. The broadened names include diols, dihydric alcohols, and dihydroxy alcohols. Ethylene glycol, HOCH2CH2OH, is the simplest member of the glycol family. Mono-, di- and triethylene glycols are the first three members of a homologous series of dihydroxy alcohols. Propylene glycol prepared by hydrolysis of propylene oxide and widely used as an ingredient of antifreeze and humectant in cosmetics is 1,2-propanediol indicating the two hydroxyl group position at 1,2, while trimethylene glycol is 1,3-propanediol with two hydroxyl group on the primary carbon atoms. 1,3-propanediol is called beta-propylene glycol. Trimethylene glycol is a clear, oily liquid; soluble in water; soluble in oxygenated solvents and completely soluble in alcohol; melting point -27 C; boiling point 210 C.

Trimethylene glycol has similar applications to Propylene glycol. It is can be used as a comonomer of unsaturated polyester resins, alkyd resins, polyester foams, polyester-based plasticizers, and as chain extender for polyurethane. It is a useful chemical intermediate which have two hydroxyl group on the primary carbon atoms and one alpha-carbon atom. 1,3-propanediol, or a derivative thereof, is used for the synthesis of lubricants, plasticizers, adhesives, photographic materials, pharmaceuticals, insect repellent, fragrances, antioxidant compound, antistatic agents, fabric softeners, and vitamin H.
