Abstract
Cyanuric chloride and methanol react at low temperature without addition of alkali such as NaHCO3 and give (4)(See part (I);similarly in the case of (1), (2).and On.The reason is that the reaction of (2) or (3) with methanol is accelerated by the acid and this is explained by comparing the reaction velocity of (1), (2), and (3) with methanol in the presence or absence of HC1.On the other hand, the alkalis used in the reaction with methanol are divided into two of the following: i) Kinds of slowing the reaction such as NaHCO3 andCaCO3 than without the addittion of alkali, and ii) kind of giving mor vigorous acceleration such as NaOH.i) acts as an acid-removing agent and prevents rapid formation of B and C (See part (I)), it is a controlling agent for proceeding of stepwise reaction of A, B and C, and it is suitable for syntheses of (2) and (3).ii) has a tendency of accelerating the reaction of alcohol and it is suitable for synthesis of (4).
