Theoretically proposed factors affecting the process of the reaction. The influence of the nature and amount of catalyst, the molar ratio of the starting materials during the reaction temperature on the yield of the product. Definitely purity, structure, elemental composition and physical constants and quantum chemical calculations of the synthesized compounds. The optimal conditions for the synthesis of a product with a high yield. KEYWORDS: acetylene, alcohols, catalysis, vinyl ethers, technological scheme. INTRODUCTION Vinyl ethers, among the organic compounds, are used as initial products in different fields such as in the fine organic syntheses and in the manufacture. Influence of nature of catalysts and solvents on these reactions was investigated, and also role of high-based system KOH-DMSO was determined. It can be explained the coming out of AAA vinyl ethers (VE) with higher yield in the presence of DMFA than DMSO. DMFA is considered as a solution in average solidity. Recently, scientific investigations on the creation of ecological safety and waste less technology, also, on the synthesis of economically cheap chemical preparations with higher yield and to introduce them into the practice have been carried out. Quantum-chemical and molecular-dynamical calculations of molecules of different vinyl ethers were carried out; also the vynilation process was modulated and the mechanisms of formation new compounds were proposОН.
