Abstract
Procedeul pentru obtinerea unor lubrifianti pentru policlorura de vinil pe baza de esteri ai pentaeritritei cu acizi grasi conform inventiei consta în aceea ca se supun esterificarii directe pentaetrita cu oleina sau acizii gratsi din uleiuri vegetale în raport molar de 1 mol pentaetrita la 1,5.....1,7 moli acid gras pentru diester respectiv 1 mol pentaetrita la 3,3....3,5 moli acid gras pentru tetraester cu adaos de 0,01...0,02% greutate clorura stanoasa dihidratata reportat la total reactanti la temperaturi de 180....200 degree C cu separarea apei prin rectificare într-o prima faza la presiune atmosferica si apoi la 10....20 mm coloana Hg (13,33-26,66 mbor) presiune reziduala pîna la scaderea aciditatii sub 5 mg KOH/g si apoi cu îndepartarea substantelor volatile distilate doar prin racire si condensare culoarea produsului putînd fi ameliorata prin adaugare de 0m01....0,02% greutate acid hipofosforos solutie 50% ca antioxidant sau prin decolorare cu 0,5% greutate carbune activ raportat la masa de produs.The process for obtaining vinyl polychlorinated pentaerythritol based fatty acid ester esters according to the invention consists in subjecting direct pentaetry esterification with olein or vegetable acids in a molar ratio of 1 mol of pentaetrate to 1.5. ... 1.7 moles of fatty acid for the diester and 1 moles of pentaetry at 3.3 ... 3.5 moles of fatty acid for the tetraester with the addition of 0.01 ... 0.02 weight percent of the stannous dihydrated chloride carried over to total reactants at temperatures of 180 ... 200 ° C with water separation by rectification in a first phase at atmospheric pressure and then at 10 ... 20 mm Hg column (13.33-26.66 mbor) residual pressure until the acidity drops below 5 mg KOH / g and then with removal of volatile distillates only by cooling and condensation, the color of the product can be improved by the addition of 0 μl 0.02% by weight of hypophosphorus acid 50% solution as antioxidant or by discoloration with 0.5% active carbon relative to the product mass.
