Description
Technical field
The present invention relates to the reduction cleaning technical fields after dyeing terylene, and in particular to a kind of sulphur of dyeing terylene cleaning
Urea derivative and preparation method thereof.
Background technology
Dyeing terylene is using disperse dyes, and after dyeing, hydrophobic disperse dyes are combined closely in hydrophobicity
PET fiber surface loose colour can not be removed using conventional water-washing method.For a long time, the reduction cleaning after dyeing terylene,
Using caustic soda and sodium hydrosulfite.This traditional approach, although effect is pretty good,：(1) COD and basicity of the dyeing waste water formed
All very high, the cost of sewage disposal of dye-works is higher；(2) after reduction cleaning, need discharge dye bath water, refill new water into
Row removes alkali neutralization, increases water consumption, reduces processing efficiency；(3) there is certain latent lesion to terylene；(4) caustic soda and sodium hydrosulfite
It is harmful influence, prodigious transport and the storage hidden danger such as pressure and potential fire, personal injury is brought to printing and dyeing mill.In mesh
Under the increasingly stringent situation of preceding Chinese environmental protection, the replacement of caustic soda and sodium hydrosulfite is extremely urgent.The present invention is exactly in such ring
It is generated under packing pressure and technical need.
Invention content
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of thiocarbamide of dyeing terylene cleaning spreads out
The molecular formula of biology and preparation method thereof, the thiourea derivative of the dyeing terylene cleaning is：
A kind of preparation method of the thiourea derivative of dyeing terylene cleaning, the preparation method include：
Step 1: weigh 90 kilograms of 2-amino-2-methyl-1-propanol, 40 kilograms of carbon disulfide and 130 kilograms it is different
Propyl alcohol；
Step 2: by 40 kilograms of carbon disulfide and 130 kilograms of isopropanol input reaction kettle, by reaction kettle after stirring
Capping；
Step 3: reaction kettle is warming up to constant temperature after 65 DEG C of 45 ∽, 90 kilograms of 2- amino -2- is at the uniform velocity added dropwise in reaction kettle
Methyl-1-propyl alcohol, 1.5 ∽ 3.0 hours are added dropwise；
Step 4: after 2-amino-2-methyl-1-propanol is added dropwise to complete, it is 70 DEG C of 50 ∽ to adjust the temperature in reaction kettle, is protected
8 ∽ of temperature reaction 12 hours；
Step 5: reaction kettle is warming up to 90 DEG C of 80 ∽ after the completion of insulation reaction, extracts and condense and collect solvent isopropanol
With 2 ∽ of by-product 3 hours, then reaction kettle be cooled to 60 DEG C hereinafter, discharging obtains thiourea derivative.
Constant temperature after reaction kettle is warming up to 50 DEG C in the step 3 as a preferred embodiment of the above solution, 2- amino -2- first
Base -1- propyl alcohol is added dropwise for 2 hours；Temperature in step 4 in reaction kettle is 60 DEG C, insulation reaction 10 hours；It is anti-in step 5
It answers kettle to be warming up to 80 DEG C, extracts and condense and collect solvent isopropanol and by-product 2 hours, then reaction kettle is cooled to 40 DEG C, goes out
Material obtains thiourea derivative.
Chemical equation is：
The beneficial effects of the invention are as follows：1, final product of the invention, in acid condition, have excellent reduction, washing,
The Multifunctional effect for disperseing releasing is not required to compounding other compositions, you can have excellent acidic reduction cleaning performance, cleaned washs
Synthetic fibre fabric has higher color fastness；2, the special deep dyeing terylenes of 8% (o.w.f) or more, general middle deep colour dyeing, after dyeing are removed
It is not required to drain, final product of the present invention and its compounding product can be directly added into acid dyeing bath, you can reach expected color jail
Degree, can save a cylinder water；3, consider auxiliary agent cost, other reducing agents (such as hydrazine sulfate) or detergent (such as poly alkyl alcohol can be added
Ethylene oxide ether AEO9 etc.) it is compounded.
Description of the drawings
Fig. 1 is the chemical equation of the present invention.
Specific implementation mode
In conjunction with attached drawing, the invention will be further described.
Weigh 90 kilograms of 2-amino-2-methyl-1-propanol, 40 kilograms of carbon disulfide and 130 kilograms of isopropanol；It will
In 40 kilograms of carbon disulfide and 130 kilograms of isopropanol input reaction kettle, reaction kettle is covered after stirring；Reaction kettle is heated up
90 kilograms of 2-amino-2-methyl-1-propanol is at the uniform velocity added dropwise in reaction kettle, is added dropwise within 2.5 hours for constant temperature after to 60 DEG C；It adjusts
Temperature in whole reaction kettle is 55 DEG C, insulation reaction 9 hours；Reaction kettle is warming up to 85 DEG C, extract and condenses collection solvent is different
Propyl alcohol and by-product 2.5 hours, then reaction kettle be cooled to 30 DEG C, discharging obtains thiourea derivative, and chemical equation is such as
Shown in Fig. 1.In use, 8% (o.w.f) general middle deep colour dyeings below, are not required to drain after dyeing, bathed in acid dyeing
In, it is directly added into final product of the present invention, carries out the acidic reduction cleaning of cloth.If you need to compound other water-soluble compound material, anti-
It answers kettle to be cooled to before 30 DEG C of dischargings, in reaction kettle plus water cooling, puts into other water-soluble compound material (including reducing agent hydrazine sulfate
