Chemo-enzymatic synthesis of oil polyols and polyurethanes of them

Popis výsledku v původním jazyce

In this work we have studied possibility to apply chemo-enzymatic catalysis for preparation of new types of oil polyols. Starting raw materials were methylesters of hydroxyfunctionalized fatty acids derived from castor oil, hydroformylated soybean oil, and epoxidized soybean oil ring opened with low molecular weight (poly)alcohols. Reacting these fatty acids with green growing centers such as 1.3-propanediol or glycerol we were able to synthesize 100 % renewable content polyols differing in molecular weight, and hydroxyl group?s functionality. We catalyzed the condensation reactions with up to 5 wt. % of immobilized Candida antarctica lipase B (Novozym 435). Setting up the reaction temperature to 70 °C and applying low pressure we allowed easy removalof a side product, methanol. Curing the synthesized oil polyols with aliphatic and aromatic type of isocyanate we prepared model polyurethane cast resins and evaluated physical-mechanical properties of these materials. We will discuss res
