Reaction Conditions:
with sodium hydroxide;triisooctyl amine in water;toluene at 17; for 1.25 h;Product distribution / selectivity;
Steps:
3
473 g of 12.1% sodium hydroxide solution were pumped within 45 minutes into a mixture of 1.15 g of triisooctylamine, 180 ml of toluene and 156.9 g of methyl chloroformate, in such a way that it was possible to keep the temperature at approx. 17 C. with cooling. The mixture was stirred for a further 30 minutes and the phases were subsequently separated. 86.7 g of dimethyl dicarbonate (91% of theory) and 5.3 g of methyl chloroformate were present in the organic phase.
