Description
Technical field
The invention belongs to chemical technology fields, specifically, being to be related to a kind of prereduction water solubility bipseudoindoxyl dye and its system
Preparation Method.
Background technique
Indigo is one of pigment most ancient known to the mankind, is widely used in food, medicine and printing and dyeing industry, it is slightly soluble in
Water, ethyl alcohol, glycerol and propylene glycol do not dissolve in grease.0.05% aqueous solution is in navy blue, and 1g dissolves in about 100ml, 25 DEG C of water,
Low compared with other edible synthesized coloring matters to the solubility of water, 0.05% aqueous solution is blue.
Client is usually the solid raw materials such as oneself purchase indigo pure powder, sodium hydroxide, sodium hydrosulfite at present, then oneself is mixed
It obtains and restores water-soluble bipseudoindoxyl dye, but in mixed process, used raw material can generate solid waste, it can be to environment
It pollutes, and expends biggish manpower；Furthermore when client oneself mixes, due to cannot be preferably by leuco compound and air
Isolation, therefore obtained bipseudoindoxyl dye is easy to go bad.
Summary of the invention
The object of the invention is that provide to solve the above-mentioned problems a kind of prereduction water solubility bipseudoindoxyl dye and its
Preparation method.
The present invention through the following technical solutions to achieve the above objectives:
A kind of prereduction water solubility bipseudoindoxyl dye, by water, indigo, sodium hydroxide, thiourea dioxide, diffusant, dispersing agent, nitrogen
And auxiliary agent mixes stage by stage, wherein nitrogen is used for as protection gas by leuco compound and air insulated.
A kind of preparation method of prereduction water solubility bipseudoindoxyl dye, comprising the following steps:
1) it stocks up, including water, indigo, sodium hydroxide, thiourea dioxide, diffusant, dispersing agent, nitrogen and auxiliary agent,
In indigo content be 10% to 40%；
2) it is beaten, after water, indigo, diffusant, dispersing agent is added in agitated kettle, stirs evenly, obtain indigo slurry；
3) indigo slurry will have been accomplished fluently to be put into reaction kettle, sequentially add and be heated to 70 after sodium hydroxide, thiourea dioxide ~
100 DEG C are reacted, and the reaction time continues 10 ~ 30 minutes, cool to 30 ~ 40 DEG C later and auxiliary agent is added, be eventually adding nitrogen
And stir evenly i.e. acquisition prereduction water solubility bipseudoindoxyl dye.
Compared with prior art, the invention has the following advantages:
Prereduction water solubility bipseudoindoxyl dye obtained by the present invention is very easy to use, and client can adjust indigo according to oneself needs
The concentration of blue dyestuff, method are that suitable water directly is added to the prereduction water solubility bipseudoindoxyl dye, and the ratio of water is higher, concentration
It is lower, on the contrary concentration is higher, and client is without the solid raw materials such as oneself purchase indigo pure powder, sodium hydroxide, sodium hydrosulfite, use process
In will not generate solid waste, not can cause environmental pollution, spent manpower is few；The prereduction water solubility bipseudoindoxyl dye
Have the characteristics that reducing property is good, dyefastness is good, dying-stable, colouring it is fast；The prereduction water solubility bipseudoindoxyl dye blowing,
There is nitrogen protection in storage, transportational process, can be avoided leuco compound and contacted with air, ensure that obtained prereduction is water-soluble
Property bipseudoindoxyl dye undergoes no deterioration before use.
