摘要:The present invention relates to the technical field of chemical synthesis, and particularly, a method for improving effect of fluorination reaction in the synthesis of 2-chloro-5-trifluoromethyl pyridine, and a matching system. The method comprises the following steps: preparing 2-chloro-5-trichloromethyl pyridine, and adding to an efficient reaction system after superfine crushing; adding an appropriate amount of iodine pentafluoride, mercury fluoride and a catalyst into the efficient reaction system; controlling the temperature and time, and carrying out a fluorination reaction on materials in the high-pressure, sealed, efficient reaction system to obtain a crude solution containing 2-chloro-5-trifluoromethyl pyridine; purifying the above crude solution to obtain 2-chloro-5-trifluoromethyl pyridine. In the present method, a fluorination reaction is carried out in a high-pressure sealed environment, such that the efficiency and effect of the fluorination reaction are effectively improved. By means of the system in the present invention, the material entering the system may be quickly superfine crushed before the reaction, so as to improve the reaction sufficiency in the subsequent reaction process.

摘要:The invention relates to a continuous process for the preparation of perfluoroalkyl iodides containing from 4 to 12 carbon atoms by thermal telomerization of tetrafluoroethylene by pentafluoroethyl iodide or heptafluoroisopropyl iodide in a tubular reactor. According to the invention, 30 to 75% of the tetrafluoroethylene is supplied at the head of the reactor; the remainder is introduced at a point in the reactor located between the 2/5 and 3/4 of the length of the tube. The proportion of undesirable heavy telomers is reduced in this way.

摘要:A process for the preparation of trifluoromethyl iodide is provided. The process includes the step of contacting in a reactor a compound represented by the formula:n nCF 3 —Wn and a compound represented by the formula:n nIF n n wherein W can be H, Br, Cl, COOH, COCl, COOCH 3 , COOC 2 H 5 , COCH 3 , COPh, CF 3 , Si(CH 3 ) 3 , SPh, SCH 3 , SSCF 3 , SSPh, SSCH 3 , or SO 2 Cl, wherein n is 1, 3, 5, or 7, and wherein the step of contacting is carried out, at a temperature, pressure and for a length of time sufficient to produce trifluoromethyl iodide. The contacting step can be carried out in the presence or absence of a catalyst and the contacting step can be carried out in the presence or absence of air.

摘要:The invention relates to a continuous process for the preparation of perfluoroalkyl iodides by thermal telomerization, in the gas phase, of tetrafluoroethylene with pentafluoroethyl iodide or heptafluoroisopropyl iodide in a tubular reactor. To improve the selectivity for a telomer of the desired extent, the telomers of lesser extent are recycled to at least one point in the reactor, which is situated between one-twentieth and three-quarters the length of the tube.
