Claims (1)
- Формальдегидный реагент для химического процесса или реакции получают в виде формальдегидно-спиртового комплекса путем приведения в контакт параформальдегида с 0,25 - 3 молярными эквивалентами алифатического спирта в присутствии каталлитического количества основания. В предпочтительном варианте осуществления изобретения химический процесс представляет собой процесс получения ароматического азометина при взаимодействии анилина с формальдегидом. Азометин затем может быть использован для получения галогенацетанилида.
