说明

2-丁酮是一种有机化合物，在化学工业中可用作氧化反应活化剂、萃取剂、溶剂和化学中间体。可由2-丁醇催化脱氢制得。

一般描述

2-Butanone is an organic compound that can be used in the chemical industry as an oxidative reaction activator, extractive agent, solvent, and chemical intermediate. It can be produced by the catalytic dehydrogenation of 2-butanol.

应用

2-Butanonecan be used as a solvent:

To synthesize waterborne polyurethanes by reacting polyols and diisocyanates via polymerization reaction.
In the Al-catalyzed chemoselective coupling of oxetanes and carbon dioxide to synthesize six-membered cyclic carbonates.

特点和优势

Low-boiling solvent
High power of dissolution
High ratio of dissolved matter to viscosity
Miscible with a wide range of hydrocarbonswithout affecting the solid′s content or viscosity
Favorable volume/mass ratio due to its low density
Fast evaporation rate
