Abstract
Способ очистки углеводородов от циклопентадиена путем обработки их карбонилсодержащим реагентом в присутствии раствора едкого натра или кали в бутиловом спирте при нагревании, отличающийся тем, что, с целью снижения расхода карбонилсодержащего реагента, в качестве последнего используют 2,2,6,6-тетраметил-4-оксипиперидин в количестве 1,2-7 моль на 1 моль циклопентадиена.The method of purification of hydrocarbons from cyclopentadiene by treating them with a carbonyl-containing reagent in the presence of sodium hydroxide solution or potassium in butyl alcohol with heating, characterized in that, in order to reduce the consumption of carbonyl-containing reagent, 2,2,6,6-tetramethyl-4 is used as the latter -oxypiperidine in the amount of 1.2-7 mol per 1 mol of cyclopentadiene.
