(54) ОХЛАЖДАЮЩАЯ СМЕСЬ(54) COOLING MIXTURE

Изобретение относитс  к составам охлаждающей смеси и может быть испо зовано в нефтехимической и газовой промышленности, Известен состав охлаждающей смес содержащей соль со льдом D-1 Однако данна  охлаждающа  смесь не позвол ет получить температуру ниже минус 50с. Известна также охлаждающа  смесь содержаща  углекислоту и орга ичесКИЙ растворитель, например ацетон, этанол 2 . Недостатком такой охлаждающей смеси  вл етс  высока  летучесть компонентов. Наиболее близким к предлагаемому изобретению по технической сущности и достигаемому результату  вл етс  состав охлаиздающей смеси, состо щей из углекислоты и пентана з. Недостатком известной смеси  вл  етс  ее высока  летучесть, требующа  большого расхода углекислоты и растворител .Кроме того, высока  ле.тучесть смеси снижает ее стаби.пьность и тепловые характеристики. Цель изобретени  - снижение лет тучести компонентов смеси. Поставленна  цель достигаетс  за счет введени  в охлаждающую смесь высших парафиновых углеводородов с температурой плавлени  от минус 5бс до плюс 58 С при следующем соотношении компонентов, вес.%; Углекислота Органический раст10-40 воритель Высшие парафиновые 0,5-20 углеводороды Предлагаемый состав охлаждающей смеси приготавливают в сосуде Дьюара емкостью 1 л, в который загружают твердую углекислоту и заливают ее смесью растворител  с высшим парафиновым углеводородом. Состав 1 готов т со следующим соотношениетл компонентов, вес.%: углекислота 60; органический растворите .пь 38; высший парафиновый углеводород 2,0. Состав 2 готов т со следующим соотношением компонентов, вес.%: углекислота 60; органи1еский растворите .ль 30; высший парафиновый углеводород 10. В таблице,представлены сравнительные данные по летучести известной и предлагаемой охла шаюшей смеси.The invention relates to cooling mixture compositions and can be used in the petrochemical and gas industry. The composition of a cooling mixture containing salt with ice D-1 is known. However, this cooling mixture does not allow to obtain a temperature below minus 50 s. A cooling mixture containing carbon dioxide and organic solvent, for example acetone, ethanol 2, is also known. A disadvantage of such a cooling mixture is the high volatility of the components. The closest to the proposed invention to the technical essence and the achieved result is the composition of the cooling mixture consisting of carbon dioxide and pentane C. A disadvantage of the known mixture is its high volatility, which requires a high consumption of carbon dioxide and solvent. In addition, the high ductility of the mixture reduces its stability and thermal characteristics. The purpose of the invention is to reduce the lifetime of the mixture components. The goal is achieved by introducing into the cooling mixture higher paraffinic hydrocarbons with a melting point of minus 5bc to plus 58 ° C in the following ratio of components, wt.%; Carbon dioxide Organic solution 10-40 lighter Higher paraffin hydrocarbons 0.5-20 The proposed composition of the cooling mixture is prepared in a 1 L Dewar vessel, into which solid carbonic acid is charged and poured with a mixture of solvent and higher paraffin hydrocarbon. Composition 1 is prepared with the following ratio of components, wt.%: Carbon dioxide 60; organic dissolve .p 38; higher paraffinic hydrocarbon 2.0. Composition 2 is prepared with the following ratio of components, wt.%: Carbon dioxide 60; organic solvent; 30; higher paraffinic hydrocarbon 10. In the table, the comparative data on the volatility of the known and proposed cooling mixture is presented.
