The catalyst FeIIFe2IIICl8 (DMA)6-iron(2+)diiron(3+)octachlorohexakis(dimethylacetamide), was isolated from the media of the catalytic synthesis of 1,1,1,3-tetrachloropropane (C3), and characterized by physicochemical methods.A counter synthesis of the catalyst was carried out.The telomerization of ethylene with CCl4 proceeds with a 98percent selectivity with respect to C3 in its presence, while the conversion of CCl4 reaches 55-60percent after 4 h.A coordination-ionic mechanism of the reaction of CCl4 with C2H4 was proposed, which followed the concept of the donor-acceptor electron-transporting systems (the DAET systems), thus accounting for its high selectivity.

Page/Page column 11-12, (2020/05/15)
The present invention provides a process for preparation of 2,3,3,3-tetrafluoropropene and intermediates thereof. Owing to its low global warming potential and zero ozone depleting potential, it is been proposed as a replacement for existing chlorofluorocarbons and hydrofluorocarbons as refrigerant.

Paragraph 0070; 0072, (2017/10/11)
PROBLEM TO BE SOLVED: To provide a manufacturing method of a chloropropane for suppressing yield reduction of chloropropane which is a target product, due to a side reaction such as a polymerization reaction or a dehydrochlorination reaction when a reaction liquid obtained by an addition reaction of an unsaturated compound in a liquid phase of carbon tetrachloride in which an iron complex is dissolved is subjected to the next reaction step or distillation step, and further suppressing the occurence of the problems of corrosion of a device or blocking of a pipeline. SOLUTION: There is provided a manufacturing method of a chloropropane by an addition reaction of an unsaturated compound represented by the general formula (1), C2HaCl4-a(1), where a is an integer of 0 to 4, in the liquid phase of carbon tetrachloride in which an iron complex is dissolved, and assistant filtration of the resulting reaction liquid.

METHOD FOR PRODUCING 1,1,1,3-TETRACHLOROPROPANE
-
Paragraph 0051-0053; 0055; 0058, (2017/10/28)
PROBLEM TO BE SOLVED: To provide a method for producing 1,1,1,3-tetrachloropropane by adding carbon tetrachloride to ethylene in a liquid phase in which a metal complex is dissolved and by efficiently removing the metal complex from a reaction mixture obtained without decomposing the target 1,1,1,3-tetrachloropropane. SOLUTION: The method for producing 1,1,1,3-tetrachloropropane comprises: applying centrifugal force to a reaction mixture obtained by carrying out the addition reaction for phase separation; and separating and removing a light phase containing the metal complex.
