Versuchsvorschrift
A 2-ethylhexanol monourethane of 2,4-toluene diisocyanate was prepared by adding 1953 parts of 2-ethylhexanol to an agitated mixture of 2610 parts of 2,4-TDI and 200 parts of methyl butyl ketone over approximately a 3-hour period with external cooling to maintain the reaction temperature below 18° C. After the addition was completed, the product was stored under dry nitrogen for subsequent use.
