Description
лические диолы, которые затем высушивают на фильтровальной бумаге и промежуточную фракцию - объединенные после 3 отмывок нижних смол, образующиес при отгонке ацетона.lyric diols, which are then dried on filter paper; and an intermediate fraction, combined after 3 washing of the lower resins, formed during the distillation of acetone.
Промежуточную фракцию подвергают дес ти последовательным отмывкам 20%-ным водным раствором ацетона так же, как и в первом случае. В результате получают дополнительное количество темно-коричневой смолы и белых кристаллических диолов, а также промежуточную фракцию - аморфные, светло-коричневые диолы , по внешнему виду похожие на прозрачную смолу.The intermediate fraction is subjected to ten successive washings with a 20% aqueous solution of acetone as in the first case. The result is an additional amount of dark brown resin and white crystalline diols, as well as an intermediate fraction - amorphous, light brown diols, in appearance similar to the transparent resin.
Всего в результате разделени получают , г:In total, the result of the separation is, g:
Циклогександиолы (белые кристаллы) концентраций 100%-ной17,0 Светла смола 72,0 Темна смола 11,0Cyclohexanediols (white crystals) concentrations of 100% -17.0 Light Resin 72.0 Dark Resin 11.0
Аналогичные результаты получают с низшими спиртами: метилОвым, этиловым, пропиловым , изопропиловым и с метилэтилкетоном .Similar results are obtained with lower alcohols: methyl ovyl, ethyl, propyl, isopropyl, and methyl ethyl ketone.
При исследовании белых кристаллов ус-тановлено: т. п. 123-124°С;In the study of white crystals, it has been established: P. 123-124 ° C;
Состав, масс.%: С 70,6; Н 10,6.Composition, wt.%: C 70.6; H 10.6.
Были сн тыЯМР- и ИК-спектры.There were NMR and IR spectra.
По совокупности всех данных сделан вывод , что белые кристаллы представл ют собой смесь изомеров с общей формулой С1оП|802 и структуройBased on the aggregate of all data, it was concluded that white crystals are a mixture of isomers with the general formula C 1PO | 802 and structure
