Description and Uses

Di(trimethylol propane), Di-TMP, 2,2-[oxybis(methylene)]-bis(2-ethyl)-1,3-propanediol is a colorless and crystalline substance (mp 112 – 114 ℃), only slightly soluble in water at ambient temperature (2.6 g/100 g at 25 ℃).It is a byproduct of 2-ethyl-2-hydroxymethyl-1,3-propanediol (TMP) production and can be isolated from the residue of the TMP distillation step. Newer investigations show that ditrimethylolpropane can be prepared in high yield and selectivity by the reaction of TMP, formaldehyde, and 2-ethylacrolein.

Di(trimethylolpropane) can be used for the synthesis of lipase catalyzed hyperbranched polymers. It can also be used in the formation of biodegradable polymers for drug delivery applications.
