실험 절차

A 2-ethylhexanol monourethane of 2,4-toluene diisocyanate was prepared by adding 585.9 parts of 2-ethylhexanol to an agitated mixture of 783 parts of 2,4-toluene diisocyanate and 60 parts of methyl butyl ketone over approximately a 5-hour period with external cooling to maintain the reaction temperature below 30° C. After the addition was complete, an additional 30 parts of methylbutyl ketone was added; and the batch stored under dry nitrogen for subsequent use.
