摘要： Method of obtaining environment-friendly polyols from waste left after transesterification of plant oils is characterized in that the said waste is heated to a temperature in the range between 160 and 240°C, preferably between 175 and 185°C, under reduced pressure in order to distill the volatile fraction. The distillation proceeds until no more condensate appears, and the resultant product has a hydroxyl number between 400 and 1200 mg KOH/g. Then the mixture is cooled below 100°C, and acidified with a protonic acid, more preferably with sulphuric acid pH 4.5 to 9, preferably from 6.5 to 7.5. Next, the reaction mixture is heated under reduced pressure to a temperature between 100 and 120°C until water stops to appear. Polyols are also produced from polyglycols extended with fatty acids and modified fatty acids.
The object of the invention is also the method of obtaining polyurethane foams by using polyols that had been obtained by the method according to the invention. The foams additionally contain substances which retard their flammability.
