Reaction rate of acyl chloride and alcohol
1. The primary alcohol 2. The acid inhibitory reaction generated with alcohol reaction is performed forward.In addition, methanesulfonyl chloride can be lost for a long time

Taking several butan isomers as an example, the activity is high to low: t-butanol, butanol-2, isobutanol, butanol
cause is the secondary secondary three-stage hydroxy carbon supply Big, compared with the acid chloride
, there is a condition, such as the ratio of methanol and tert-butol ratio, because the methanol molecule is small, and the acyl chloride contact is large, the reaction rate is also large
Alcohol is also limited by the molecular size, including an acid molecular size , for example, alcohol and water, the initial period is just starting to contact, the water is fast, but once the reaction is carried out, The product is produced, and the case is complex If the acid chloride is a small molecule chloride, the alcohol is also carbon 3 or less, this situation, hydrolysis, because the product is water soluble, the acid chloride is substantially in equal Hydrolysis Large molecule chloride is different, and if hydrolysis produced acid or alcohol is insoluble in water or slightly soluble in water, then the acid or alcohol (esterification) is dissolved with acid or alcohol (esterification). Reduce hydrolysis velocity and product composition (esterification side reaction) , then the reaction of germacly chloride and macrol, it is not necessary to solve it, it is not necessarily, to see how much molecules, specific Compound decisions small molecule of carboxylic acid acid chloride, with long carbon chain chloride, aromatic acid acid acid acid acid chloride, and sulfonyl chloride (slow solution), to be specific, not simple and slow
