Problems solved by technology

Jinlu Chemical uses isooctyl sulfate as a mercerizing penetrant. Since the esterification agents such as chlorosulfonic acid and concentrated sulfuric acid used as raw materials for its production are stored in iron packaging, iron ions are inevitably brought into the product, and iron Ions can catalyze and decompose hydrogen peroxide in the process of oxygen bl

preparation example Construction

[0030] The preparation process of the mercerized penetrant of the present invention is mainly to first add a certain amount of deionized water to the fatty alcohol and the fatty alcohol polyoxyethylene ether, raise the temperature to 50-80°C, and add the phosphorylation reagent under uniform stirring. , heat up to 100-120°C, keep warm, carry out esterification reaction for 2-4 hours, then add organic acid anhydride into the three-necked flask, continue to keep warm, carry out esterification reaction for 2-4 hours, then add deionized water, and hydrolyze for 2-4 hours , after cooling sufficiently, the target mercerizing penetrant product can be obtained.

[0031] The amount of the mercerizing penetrant provided by the present invention in the alkali solution in the mercerizing process can be 0.05-5%, or 0.1-2%, or 0.1-1%. The content of sodium hydroxide in the alkaline solution can be used in a conventional amount without any particular limitation, for example, it can be 100-35...

Embodiment 1

[0034] Weigh the mixed fatty alcohol (30g of isotridecanol + 20g of polyethylene glycol).

[0035] Weigh 10 g of fatty alcohol polyoxyethylene ether isotridecyl alcohol ether (EO6). The fatty alcohol polyoxyethylene ether contains isomeric tridecyl alcohol ether, isomeric decanol ether, or a mixture of one or both of them.

[0036] Put fatty alcohol and fatty alcohol polyoxyethylene ether in a three-necked flask, add 10g of deionized water at the same time to start stirring, raise the temperature to 70°C, and add 15g of phosphorus pentoxide while stirring evenly, and turn on the condenser to reflux. Heat up to 110°C, keep it warm for 3 hours, then add 15g of maleic anhydride to the three-neck flask and continue to keep it warm for 3 hours, then add 10g of deionized water, hydrolyze for 3 hours, and the target mercerized penetrant product will be obtained after cooling sufficiently.

Embodiment 2

[0038] Difference with embodiment 1 is that raw material is different:

[0039] Composition of mixed fatty alcohols: 20 g of isomeric decanol, 15 g of polypropylene glycol;

[0040] Fatty alcohol polyoxyethylene ether: isomeric tridecyl ether 15 g;

[0041] Phosphorus pentoxide 15 g;

[0042]Maleic anhydride 15 g;

[0043] Deionized water: 10g and 5g are added in the first and second additions respectively.

Abstract

The invention relates to a phosphate silkete penetrating agent and a preparation method thereof, and belongs to the technical field of textile auxiliary agents. The phosphate silkete penetrating agent comprises the following components in parts by weight: 5 parts of fatty alcohol, 1-4.5 parts of fatty alcohol-polyoxyethylene ether, 1-1.5 parts of a phosphorylation reagent and 1-2 parts of organic acid anhydride. As substances such as phosphorus pentoxide, organic acid anhydride and fatty alcohol-polyoxyethylene ether which are relatively gentle in reaction and easy in reaction speed control are adopted to react, the phosphate silkete penetrating agent which is small in bubble, good in permeability and free of irritant smell can be prepared.

Description

technical field [0001] The invention relates to a phosphate ester mercerizing penetrant and a preparation method thereof, belonging to the technical field of textile auxiliaries. Background technique [0002] Penetrants are a class of surfactants that allow liquids to penetrate quickly and evenly into a solid substance. In textile printing and dyeing production, penetrants are widely used, such as desizing, scouring, bleaching, wetting of dyes and other processes. Mercerizing is an important link in the pre-treatment of fabric dyeing and finishing. The alkali concentration of the mercerizing treatment solution is generally higher than 180g / L. It can quickly enter the interior of fabric fibers. On the other hand, due to the severe shrinkage of cotton fibers, the permeability of lye is even worse, so it can only achieve the effect of mercerizing the surface. Therefore need a kind of penetrating agent to be able to reduce the viscosity of lye, enhance the ability of lye...
