Yn. Chirkov et al., THE EFFECT OF ACIDS ON THE RATE OF ADDITION OF ALCOHOLS TO ISOCYANATES, Bulletin des Societes chimiques belges, 105(8), 1996, pp. 477-481
We report some preliminary results related to the influence of acids o
n the reaction rate of urethane formation from alcohols and isocyanate
s, in the presence of alkyltin carboxylates. Small quantities of hydro
gen chloride or of carboxylic acids slow down the kinetics in an appre
ciable manner. Some hypotheses are considered in order to interpret th
ese results.
