Description
Предлагаемое изобретение относитс к способу приготовлени препарата дл окраски дерева с применением щелочной обработки нитротолуолов и их гомологов .The present invention relates to a method for preparing a preparation for painting a tree using alkaline treatment of nitrotoluenes and their homologs.
Известно, что фракции сольвент-нафты , в состав жидких продуктов нитровани которой вход т производные нитротолуолов , при обработке нитрационной смесью обычного состава образуют масл нистые и кристаллические ароматические нитросоедипеии сложного состава .It is known that the fractions of solvent naphtha, in the composition of the liquid nitration products of which nitro toluene derivatives are included, when treated with a nitration mixture of the usual composition, form oily and crystalline aromatic nitroedonypees of a complex composition.
Ныне найдено, что указанна масл ниста часть продукта нитровани сольвент-нафты , будучи отделена от кристаллической части, может быть использована по предлагаемому способу дл изготовлени препарата, окрашивающего дерево. Така возможность получени препарата крас щего дерево, из масл нистых нитросоединений основана на способности последних -изомеризироватьс под вли нием щелочи в кислые изонитро-соединени , образующие со щелочными металлами темнокоричневые растворимые в воде соли, которые и, вл ютс веществами, крас щими дерево.It has now been found that the oily part of the nitriding product of solvent naphtha, being separated from the crystalline part, can be used according to the proposed method for making a preparation that paints wood. This possibility of preparing a dye tree from oily nitro compounds is based on the ability of the latter to isomerize, under the influence of alkali, to acidic isonitro compounds, which form water soluble dark brown salts with alkali metals, which are substances that stain the tree.
Способ состоит в том, что масл ниста часть продуктов нитровани сольвент-нафты обрабатывают раствором едкого натра или другой какой-либоThe method consists in the fact that the oil part of the nitration products of solvent naphtha is treated with sodium hydroxide solution or some other
щелочи, после чего полученную массу раствор ют в воде и, по выпаривании досуха избытка воды, краску выдел ют, в виде твердых темно-коричневых крупинок .alkalis, after which the resulting mass is dissolved in water and, after evaporation of excess water to dryness, the paint is isolated, in the form of solid dark brown grains.
Приме р.-Дл получени препарата, крас щего дерево, из сольвент-нафты, кип щие в различных пределах фракции ее подвергают нитрованию обычного состава нитрационной смесью из 1 части НМОз и 2 частей дым щей HaSOi, при чем температуру в процессе нитровани постепенно повыщают - приблизительно до 80-90°. В результате нитровани образуетс смесь кристаллических и масл нистых нитросоединений, которые отдел ют друг от друга и масл нистую часть примен ют в качестве исходного продукта дл получени препарата, крас щего дерево. С этой целью масл нистую часть обрабатывают раствором едких щелочей путем смешени граммолекул рных количеств ингредиентов при обьГкновенной температуре. После непродолжительного сто ни смеси, тем пература ее само собой начинает быстро повышатьс и достигает 100 и выще. По прекращении дальнейщего повышени температуры, реакционную массу разбавл ют немного водой и выпаривают, досуха. Краска получаетс и виде коричневых крупинок.Example p. To obtain a preparation for coloring a tree from solvent naphtha boiling in different limits of the fraction, it is subjected to nitration of the usual composition with a nitration mixture of 1 part HNO3 and 2 parts of HaSOi smoke, while the temperature in the nitration process gradually increases - approximately 80-90 °. As a result of nitration, a mixture of crystalline and oily nitro compounds is formed, which are separated from each other and the oily part is used as a starting product for the preparation of a tree dye. To this end, the oily part is treated with a solution of caustic alkalis by mixing gram-molecular amounts of ingredients at an appropriate temperature. After a short standing of the mixture, its temperature itself begins to rise rapidly and reaches 100 and higher. Upon termination of further increase in temperature, the reaction mass is diluted slightly with water and evaporated to dryness. The paint is obtained in the form of brown grains.
