, p. 439 - 441 (1992)
A catalytic cycle for the direct carbonylation of CCl4 into CCl3COCl, catalysed by metallic salts mixtures. e.g.AlCl3/MCln/CuCl, under unexpectedly mild conditions, is proposed on the basis of FTIR, 17O and 27Al NMR spectroscopic studies.
A high-purity 3, 5, 6 - trichloro-pyridine -2 - sodium alcoholate production process (by machine translation)

Paragraph 0046; 0064, (2019/04/04)
The present invention relates to the technical field of chemical material production, and in particular relates to a high-purity 3, 5, 6 - trichloro-pyridine - 2 - sodium alcoholate production process, comprises the following steps: chlorine acetyl chloride; preparing trichlor; addition cyclization: the protection of inert gas atmosphere by adding solvent, the pure product of the chloroacetyl chloride, acrylonitrile and catalyst, the temperature of the stirred to back flow, so that the reflux to return to below the liquid level, reduced pressure distillation, heat filter, the catalyst can be recycled for use, get filtrate for use; preparing 3, 5, 6 - trichloro-pyridine - 2 - sodium alcoholate crude; for preparing high-purity 3, 5, 6 - trichloro-pyridine - 2 - sodium alcoholate. The invention solves the problems in the prior art 3, 5, 6 - trichloro-pyridine - 2 - sodium alcoholate preparation technical difficulty is high, the yield is low and low purity of, the prepared 3, 5, 6 - trichloro-pyridine - 2 - sodium alcoholate has high purity, high yield and relatively shallow the advantages of luster, reasonable production process and is favorable for industrial production.

A synthetic method of trichloroacetyl chloride
-
Paragraph 0033-0060, (2017/02/24)
A synthetic method of trichloroacetyl chloride is provided and belongs to the field of organic synthesis. The method includes steps of subjecting chlorine and chloroacetic acid in a melt state to a contact reaction to prepare a primary chlorination material, heating and reacting the primary chlorination material with sulfur monochloride and chlorine to prepare a secondary chlorination material, and heating and reacting the secondary chlorination material with chlorine under actions of a catalyst to obtain the trichloroacetyl chloride. The method synthesizes the trichloroacetyl chloride in a non-water system by utilizing the chloroacetic acid. The non-water system is adopted, thus avoiding generation of toxic and harmful compounds in a preparation process, avoiding a dewatering step, improving environment protection performance of the preparation process, simplifying the synthetic process and facilitating reduction of a synthesis cost.
