Анотация: . In article results by investigation of catalytic homogeneous vinylation of 2,4,6-trihydroxy-1,3,5triazine (cyanuric acid) by acetylene on the base high-based system: DMSO, DMF; hydroxides of lithium, potassium and sodium. It was determined that in process of synthesis mono-, two- and three-vinyl ethers of cyanuric acid have been formed. Optimal parameters of investigated process were determined: influence of duration of reaction temperature and rate of feeding acetylene, nature of using catalysts and solvents on yield of forming products. Structure of the synthesized vinyl ethers was been proved by data of such methods IR, 1H, 13CNMR spectral analyzes. Obtain results were treated wish using mathematical models and methods. Analysis of obtained experimental results of investigated chemical process has shown corresponding to theoretical data. Diagrams of results of activation energy and dynamics of changing of kinetic parameters have been elaborated and also graphs of analytical functions are also presented. Values of products yields have been determined: it was shown that at temperature of 80–120 oC for and duration of reaction 6 h, yield of vinyl ethers of cyanuric acid have increased: (12.2–18.2) of mono-vinyl ether, (14.6–21.8) two-vinyl ether and (12.4 - 22.6) % three-vinyl ether, correspondence. It was determined that further increase of temperature (140 oC) has carried out to he creasing of yields of products to 16.4; 16 and 10.8 % correspondence for mono-, two- and thee-vinyl ethers. It was determined that optimal optimal regime for carrying out of experiments was: duration of reaction 6 hours, temperature 120 oС, quantity of catalyst relatively of initial reagent (cyanuric acid) - 10 mas %, (from it’s mass) and rate feeding of acetylene 4.5 l / sec. The conditions for the maximum yield of total vinyl ester (62.6%) of cyanuric acid were determined.
Ключевые слова: acetylene vinylation ethers of cyanuric acid , mono,- two- and three vinyl cyanurates.
