High-purity level of 1,1,3-trichloroacetone preparation
Abstract:acetone catalyzed chloride and produced by solvent crystallization at 1,1,3-trichloroacetone with high purity of no less than 99.0%,with a yield of 45%o Key words:1,1,3-trichloroacetone;synthesis;high purity
----------. Foreword
1,1,3■trichloroacetone is an important intermediate in the production of folic acid.At present,1,1,3.acetone trichloropacetone,long production cycle(48 hours),poor selectivity,low yield,1,1,3-trichloropacetone content is only about 17%,after water extraction,its content is only 51.9%.And the production cost is high,the product correction is low.These all lead to high domestic folic acid production costs,difficult to improve the content and other problems.The author read a large number of domestic and foreign documents. After many experiments and studies,we added catalyst and controlled fou chlorine speed,reducing the reaction time to 1,1,3-3 trichloropacetone in 24 hours, and 1,1,3-3 trichloropacetone crystallization with purity greater than 99%and the yield of more than 45%.

- Experimental steps
In a four-neck flask with a 500ml spherical condenser,a certain amount of acetone and catalyst were stirred and fed to chlorine at a reaction temperature of 10~30 W.Start timing,stop passing through chlorine several hours after the reaction,and continue stirring for 1 hour.A special solvent like material was added to the resulting mixture,stirred for 1 hour while cooled to 10°C crystallization,extracting 1,1,3-trichloroacetone.
- 1,1,3.Selective determination of trichloroacetone purity
Varin 3700 gas chromatograph,QF・1 filling column and FID detector were used to selectively determine the purity profit of the product and chloride solution.
- Results of the discussion
- The influence of catalyst on chloride selectivity showed the selectivity of acetone chlorination
Big influence,Table 1 lists a set of experimental results.From Table 1,the minimum selectivity of 1,1,3-trichloroacetone is significantly increased(about 19.1%)without catalyst,and
compound amine catalyst is the best,up to 57.5%o.Test conditions: Innl acetone, 3nr) l chlorine,catalyst 0.6g,temperature 1030°C,
time 18 hours.Within 12 hours va:3.9 Cao h;2
〜7 hours,vq:27 Cao h;7〜18 hours,VQ:3.9 to h.Table 1.Effects of the catalyst on the product selectivity
- Effect of the through-chlorine velocity on the reaction
The experiment found that uniform chlorine had poor product selectivity,significantly improving the product selectivity and yield.
