An impregnation liquid comprises diacetone alcohol, in a proportion of between 20 wt. % and 50 wt. %, glycerol trioleate, in a proportion of between 20 wt. % and 50 wt. %, castor oil, in a proportion of between 10 wt. % and 40 wt. %, acetone, in a proportion of between 3 wt. % and 5 wt. %, and at least one sulfonate, in a proportion of between 0 wt. % and 1.5 wt. %. A method for surface treatment of a ferrous part includes an impregnation step by such an impregnation liquid, and the treated part obtained.

This application discloses a method for preparing diacetone alcohol by acetone condensation, comprising the following steps: in a reactor, acetone is contacted with a catalyst, stirred, and reacted to obtain diacetone alcohol; the catalyst is selected from a molecular sieve treated with ammonia; the molecular sieve is selected from at least one of MCM-41 molecular sieve, MCM-48 molecular sieve, and SBA-15 molecular sieve. This method has advantages such as high acetone conversion rate and diacetone alcohol yield, good catalyst recycling performance, simple post-reaction treatment, and no waste salt or wastewater generated.

The present application relates to a kind of methods for synthesizing corresponding alcohol by electrocatalytic hydrogenation of carbonyl compound, using flow electrolytic cell or split H-type electrolytic cell, adding carbonyl compound in cathode electrolyte, collecting liquid phase alcohol product at reaction output end.The carbonyl compound includes formaldehyde, acetaldehyde, acetone, n-propyl aldehyde, n-butyl aldehyde, n-pentanal, 4-hydroxy-2-butanone, diacetone alcohol, 2-pentanone, cyclobutanone, furfural and other carbonyl-containing compounds.Different types of electrolytic cell are used, and the iron-based electrocatalyst constructed has the characteristics of low cost, high activity and high selectivity.Compared with traditional thermal catalytic technology, the electrocatalytic hydrogenation of carbonyl compound to synthesize corresponding alcohol technology is carried out at room temperature and normal pressure, using water as hydrogen source, which not only reduces energy consumption and production cost, but also is green, safe and efficient, in line with the requirements of green chemical industry.
