Description
Я черном ХЛОПКОВОМ масле может содержатьс до фосфатидов и до 2% госсипо.та и его ближайших дериватов. Эти нежировые вещества вызывают затруднени п повышенные потери нри рафина1П1Н черного хлонкового масла. Однако доступных дл заводских лабораTopini методов определени фосфатндов в черном хлопковом мас.че не существует, а методов определени суммарного содержани rocciiпола и его дериватов вообще не имеетс , так как методы определени нативного госсипола дл указанных целей не пригодны.I can have black COTTON oil up to phosphatides and up to 2% of gossypoto and its closest derivatives. These non-fatty substances make it difficult to increase the loss of n-raffin black nylon oil. However, there are no methods available for factory labyrinopopini to determine the phosphatendus in black cotton, and methods for determining the total content of the roccii field and its derivatives do not exist at all, since the methods for determining the native gossypol are not suitable for these purposes.
Предлагаемый способ позвол ет определ ть содержание в черном хлопковом масле фосфатидов и суммарное содержание госсипола Г5месте с его дериватами, что имеет важное значение как дл оценки товарного достоинст15а 4epiH ix х.топковых масел, так и дл правильного ведени процесса рафинации.The proposed method allows determining the content of phosphatides in black cottonseed oil and the total content of gossypol G5 along with its derivatives, which is important both for assessing the merits of 4epiH ix x topkovyh oils and for the proper refining process.
Способ состоит в следующем. Определ етс удельный и показатель преломлени черного хлопкового масла и кислотное число. Онределение пронзводитс дублетом с предельно возможной точностью . Удельньп вес определ етс в ШКнометре на 100 мл или в мерной колбе такой же емкости. Показатель преломлени определ етс - при помощи рефрактометра любой конструкции, обеснеч1 вающего точиость отсчета 0,0001.The method consists in the following. The specific and refractive index of black cottonseed oil and the acid number are determined. Determination is carried out with a doublet with the highest possible accuracy. The weight is determined in a 100 ml Scnnometer or in a volumetric flask of the same capacity. The refractive index is determined with the help of a refractometer of any design, which will deplete a reference point of 0.0001.
Затем масло подвергаетс щелочиой рафинации. Дл рафииаини беретс около 500 мс масла. Рафинаци ведетс по следующему режиму; температура . Mac.ia инача.ле 20 . а в Koinj,e 50 . коннентраци 1н,елочи 400 г/,-, избыток протнв теоретического 300%; врем отстаиванн соапстока после рафинацни-1 час. Нейтрализованное масло сливаетс с осевшего соапстока и профильтровываетс через большой ск.:1адчатый. фильтр. Собираетс около 220 --250 мл профильтрованного масла, затем оп зедел етс удельный вес, показате.;|11 преломлени и кислотное чис.:10 полученного рафинированного масла. Удельны) вес и показатель преломлепи сырого н рафинированного масел определ ют при одной и той же температуре.The oil is then subjected to alkali refining. For rafiain, about 500 ms of oil is taken. Rafinaci is maintained according to the following regime; temperature . Mac.ia another. 20. and in Koinj, e 50. Concentration: 1N, bales: 400 g /, -, theoretical excess of theoretical 300%; time settled soapstock after refining-1 hour. Neutralized oil is drained from the settled stock flow and filtered through a large screen: 1 side. filter. About 220-250 ml of the filtered oil is collected, then the specific gravity is measured, as indicated; refractive index and acid number: 10 of the obtained refined oil. The specific weight and the refractive index of crude refined oils are determined at the same temperature.
