摘要

在加热到250°C和4mpa的热水中，甲醛的cannizzaro型反应在没有催化剂的情况下产生甲醇和甲酸，尽管众所周知，这种歧化反应在环境条件下存在大量碱性催化剂时发生。甲酸进一步与甲醛发生氢化物转移反应，最终甲醇收率超过50%。

Noncatalytic Cannizzaro-type Reaction of Formaldehyde in Hot Water (INTERFACE SCIENCE-Solutions and Interfaces)

In hot water heated up to 250 °C and 4 MPa, methanol and formic acid are produced from the Cannizzaro-type reaction of formaldehyde without a catalyst, although this disproportionation reaction is well-known to occur in the presence of a large amount of base catalysts in ambient conditions. Formic acid further undergoes the hydride transfer reaction with formaldehyde, and the final yield of methanol exceeds 50%.
