Abstract
Vinilxlorid monomerining katalitik sintezida katalizatorlarning rivojlanish tarixi kimyo sanoati rivojida muhim o‘rin tutadi. 1912-yilda F. Klatte PVX polimerini kashf etishi natijasida vinilxloridning sanoat ahamiyati aniqlandi. 1930-yillarda atsetilen va xlorid vodorod asosida HgCl₂ni aktivlangan ko‘mirga yutqizilgan katalizatoridan foydalanib vinilxlorid monomeri ishlab chiqarish yo‘lga qo‘yildi. Ushbu texnologiya yuqori samaradorlikka ega bo‘lsada, simobning toksikligi va ekologik xavfi jiddiy muammo bo‘lib qoldi. 1970–1990-yillarda ushbu muammolarni hal etish maqsadida oltin, palladiy, ruteniy kabi metall asosidagi simobsiz katalizatorlar ustida tadqiqotlar olib borildi.
