| titleOfInvention | Method of tributylchlorostannane preparation |
| abstract | The invention relates to organotin compounds, in particular, to methods for the preparation of tributylchlorostanine used in the synthesis of organotin biocides. The purpose of the invention is to simplify the method and increase its productivity. The process is carried out in continuous mode in a vertical reactor filled with granular magnesium to the expanding part of the reactor. A solution of chlorine tin and halobutane is fed to the lower part of the reactor, and ether or a mixture of hydrocarbon solvent and halobutane is fed with two or three separate streams simultaneously at different heights of the reaction zone. At the same time, given molar ratios, the molar ratios of SnCU and halogenbutane 1: (3.2-5) and halobutane and ether 1: (0.2-1) are maintained. Up to 50% of the total amount of halobutane is fed into the ether stream. In as aaaogenbutan used and, as. growth ester -, iso-CzH / 0, tetrahydrofuran, as a hydrocarbon solvent - heptane, toluene, m-xylene, or their mixture. These conditions increase the productivity of the process by 2 times (up to 58.7 g / n-h) while reducing the amount of solvent s 30 times and eliminating a number of operations. 1 hp F-ly, 2 tab., 1 Il.
