Each of these reagents provides sufficiently high technological parameters.
Известен отход производства синтетического каучука - топливо Т-4, представл ющее собой смесь кубового остатка ректификации диметил-1,3диоксана , кубового остатка ректификации возвратного диметил-1,3-диокса на и кубового остатка регенерации возвратного толуола. Соотношение к® moнeнтoв в этой смеси колеблетс в широких пределах от 60:25:15 до 80:10:10 4. .A known waste from the production of synthetic rubber is fuel T-4, which is a mixture of the bottoms of the distillation of dimethyl-1,3 dioxane, the bottoms of the rectification of returnable dimethyl-1,3-dioxa and the bottoms of the recovery of returnable toluene. The ratio to the mono in this mixture varies widely from 60:25:15 to 80:10:10. 4..
Ойнако известное вещество в качестве флотационного реагента ранее не примен лось.However, a known substance was not previously used as a flotation reagent.
Цель изобретени - повышение извлечени горючей массы и качества . получаемого концентрата при одновременном снижении Затрат на реагенты.The purpose of the invention is to increase the extraction of combustible mass and quality. the resulting concentrate while reducing reagent costs.
Поставленна цель достигаетс использованием смеси кубового остатк ректификации диметил-1,3-диоксана, кубового остатка ректификации возвратного диметил-1,3-диоксана и кубо вого остатка регенерации возвратного толуола в качестве реагента вспенивател дл флотации угл .The goal has been achieved by using a mixture of dimethyl-1,3-dioxane distillation residue, residual dimethyl-1,3-dioxane distillation distillation residue, and returnable toluene recovery bottoms residue as a blowing agent for coal flotation.
Топливо смесь Т-4 состоит из трех основных технических продуктов: кубового остатка ректификации 4,4-диметил-1 ,3-диоксана (кубового остатка после ректификации изЪпрена) Т-80 кубового остатка ректификации возвратного 4,4-диметил- 1,3-диоксана (кубовые остатки колонны очистки диметилдисксана) и кубового остатка регенерации возвратного толуолаабсорбента побочные продукты произ водства изопрена в смеси с отходами производства бутадиена и изопрена).The fuel mixture T-4 consists of three main technical products: the bottom residue of the rectification of 4,4-dimethyl-1, 3-dioxane (the bottom residue after rectification of iprene) T-80 of the bottom residue of the rectification 4,4-dimethyl- 1,3- dioxane (vat residues from the dimethyldixxane purification column) and VAT residue from the recovery of returnable toluene-absorbing agent by-products of isoprene mixed with waste products of butadiene and isoprene).
