2-Ethylhexanol → Toluene 2,4-Diisocyanate

Participants

Reaction Steps

A 2-ethylhexanol monourethane of 2,4-toluene diisocyanate sample was prepared by adding 651 parts of 2-ethylhexanol to an agitated mixture of 870 parts of 2,4-TDI and 100 parts methyl butyl ketone over approximately 3 hours, with external cooling to maintain the reaction temperature below 18° C. After addition was complete, the batch was agitated an additional 2 hours and stored under dry nitrogen for subsequent use.
