GETEROGEN-KATALITIK USULDA AYRIM ATSETILEN SPIRTLARINI GEKSIN-1 ISHTIROKIDA ENANTIOSLEKTIV ALKINILLASH REAKSIYALARI
##submission.downloads##
Ushbu ishda ilk bor molekulasida to‘yingan, to‘yinmagan va aromatik o‘rinbosarlar saqlagan atsetilen spirtlarini Ti(OBu) 4 /C akt.
katalitik sistemasida geksin-1 bilan alkinillash reaksiyalari tadqiq qilingan. Tadqiqot natijalari asosida atsetilen spirtlarining
viniloksi efirlari sintez qilingan. Mahsulot unumi va reaksiyaning borishiga boshlang‘ich moddalar mol nisbatlari, reaksiya
davomiyligi, harorat, katalizator va erituvchilar tabiati ta’sirlari tadqiq qilingan. Tanlangan atsetilen spirtlarining reajsiyaga
kirishish faollik qatori ishlab chiqilgan. Sintez qilingan birikmalar identifikatsiyalangan, ularning xususiy konstantalari, tuzilishi,
tozaligi va tarkibi zamonaviy fizik-kimyoviy tadqiqot usullari yordamida isbotlangan, reaksiya mexanizmlari taklif qilingan.
