Description
Известны способы получени методом полимеризации кумароповой смолы, содержащейс в т желой фракции сырого бензола, смеси кумпрона , индена и стирола. Катализатором при зтом служит серна кислота или хлористый алюминий.Methods are known for the method of polymerization of the coumarope resin contained in the heavy fraction of crude benzene, a mixture of cumbron, indene and styrene. The catalyst for this is sulfuric acid or aluminum chloride.
Предлагаетс способ получени кумароновой смолы из фракции каменноугольного масла полимеризацией смеси кумарона, индена и стирола, с применением в качестве катализатора двуокиси азота.A method is proposed for producing coumarone resin from a coal oil fraction by polymerizing a mixture of coumarone, indene and styrene, using nitrogen dioxide as a catalyst.
В реакционный сосуд над поверхностью кумароновой ф эакции пропускают газообразную двуокись азота и слегка помешивают содерж мое сосуда. По окончании полимеризации от отработанной фракции острым паром отгон ют т желый бензол. Остаток представл ет собой кумароновую смолу. Выход составл ет 32-35% от исходной фракции. Полимеризаци с двуокисью азота идет быстро и до конца. Получаема кумаронова смола имеет температуру разм гчени в пределах 65-68°.Gaseous nitrogen dioxide is passed into the reaction vessel above the surface of the coumarone faction and the contents of the vessel are slightly stirred. At the end of the polymerization, heavy benzene is distilled off from the spent fraction with live steam. The residue is coumarone resin. The yield is 32-35% of the starting fraction. Polymerization with nitrogen dioxide goes quickly and to the end. The resulting coumarone resin has a softening point in the range of 65-68 °.
