Description

Известны способы, перевод щие в раствор сернистые красители с помощью альдегидов в щелочной среде.Processes are known that convert sulfuric dyes into solution using aldehydes under alkaline conditions.

В предлагаемом способе перевод в раствор сернистых красителей производитс  нагреванием их с водным раствором фурфурола или формальдегида и едкой щелочи.In the proposed method, the conversion into a solution of sulfur dyes is carried out by heating them with an aqueous solution of furfural or formaldehyde and caustic alkali.

Пример 1.-Беретс  сернистого зеленого 5-Р(анилтреста)-1 кг, формальдегида-40 % -400-500 см, едкого натра 100-150 г, воды-б-7 л и нагреваетс  до растворени  красител .Example 1. Berets of sulphurous green 5-P (aniltrest) -1 kg, formaldehyde-40% -400-500 cm, caustic soda 100-150 g, water-7 l and heated until the dye is dissolved.

Пример 2. - Беретс  сернистого желтого F (анилтреста) - 1 кл, фурфурола - 240 - 300 ct/, едкого натра -Example 2. - Berets sulfur yellow F (aniltrest) - 1 cl, furfural - 240 - 300 ct / caustic soda -

150-200 г, воды-5-7 л и нагреваетс  до растворени  красител .150-200 g of water is 5-7 liters and heated to dissolve the dye.

Пример 3.-Вз в сернистого зеленого в пасте (анилтреста) - 1 KZ, формальдегида-40%-150-200 см, едкого натра 100 н и воды 3-5 л и нагревают до полного растворени  красител .Example 3. Beam in green sulphate in a paste (aniltrest) - 1 KZ, formaldehyde-40% -150-200 cm, caustic soda 100 N and water 3-5 liters and heated until complete dissolution of the dye.

Предмет изобретени .The subject matter of the invention.

Способ перевода в раствор сернистых красителей с помощью альдегидов в щелочной среде, отличающийс  тем, что сернистые красители нагревают с водным раствором фурфурола или формальдегида и едкой щелочи.A method of converting sulfuric dyes into a solution with aldehydes in an alkaline medium, characterized in that the sulfur dyes are heated with an aqueous solution of furfural or formaldehyde and caustic alkali.
