METHOD FOR OBTAINING TEXTILE AND AUXILIARY SUBSTANCE by the interaction of alkylpolyoxyethyleneglycol ethers of the general formula KO (

Description

The invention relates to a process for the manufacture of textile auxiliaries based on alkylpolyoxyethylene glycols, which finds application in the processes of preparing staining and the subsequent processing of crumbled materials. The textile auxiliary substance (TBB) is known - synthanol DC-10 of the general formula KO (SNg. SNa.O) „H, where V ekalip Cw-Qg, p 10-12, which has good detergency and good resistance to electrolytes there D1 The disadvantages of this TBB are relatively low wetting ability and twisted surface tension and foaming (Table 2), as a result of which TBB does not provide uniform saturation of textile materials during the process of insulating on ejector and rotary speed machines. Also known are TBB of the general form RO (CiH2CiHO) (fHOR where Qualkil Cg-Cje, snz-; K-alkyl) (, p 1-100, and the method of producing compounds of this formula), which consists in the interaction of alkylpolyoxyalkylene glycol ethers of the general formula KO (where Valkyl Cg-Cjoi CH3-v p 1-100, with vinyl alkyl ethers of the general formula, where 82 C | -C | taken at a molar ratio, respectively, equal to 1: (1.1-1.2) in the presence of mineral acids at a temperature of 30-60 ° C. The specified TVB have good defoaming properties of C21. The disadvantages of these TVB are their relatively small solubility in water, lack of wetting and detergent action, increased surface tension, poor resistance to electrolytes, and high chromaticity (Table 2). The purpose of the invention is to increase the wetting ability and decrease surface tension. the production of a textile auxiliary by the interaction of alkylpolyoxyethyleneglycol ethers of the general formula RO (dH2ClHO) H, where F is alkyl,. , with vinyl esters of the general formula E20CH CHg, where I is alkyl Cz-C, taken at a molar ratio of 1: (O, 3-0.9) at a temperature of 30-60 ° C in the presence of phosphoric acid. Example 1. A 250 ml flask with a stirrer, a thermometer, a reflux condenser and a dropping funnel was charged with 127.4 g (0.2 g-mol) of alkyl polyoxyethylene glycol ether (B Cd2-Cf ,,) (cloud point C hydroxyl number 88). The flask was placed in a g-bath, heated to 1.96 g of 73% orthophosphoric acid (0.0146 g-mol) was added, and 16.02 (0.16 g-mol) of vinyl-h-butyl ether was added. within 5 min. The ratio of polyoxyglycol ether: vinyl ether 1: 0,8. The reaction mass is heated to 45 ° C with stirring and kept for 3 hours, then cooled to 1.3 g of sodium hydroxide (0,0146 g-mol) is added dropwise. The addition of the alkali solution is carried out at a temperature of 15-20 ° C to a pH value of a 10% aqueous solution of 6.5. Then the reaction mass is filtered through a nylon cloth using a Kochner funnel from sodium phosphates and 140.5 g of the desired product is obtained (yield 95.6%) as a light yellow liquid with a cloud point of 35 ° C. The hydroxyl number was found, and mgKOH 18.8;

The resulting product is a mixture,%: the starting alkylpolyoxyethyleneglycol ether (PEG) K OgCn, 21.4 and acetal 78.6%.

Found 0.83, calculated 0.84. This value of N corresponds to the content,%: PEG 75 and acetal 25.. Example 2. Under the conditions of example 1 of 127.5 g (0.2 g-mol) polyoxyethylene glycol ether alkyl (E C g-C4h), 6.0 g (0.06 g-mol) of vinyl-H-butyl ether (molar ratio of polyoxyethylene glycol ether: vinyl, ether 1: 0.3) and 1.4 g of orthophosphoric acid after neutralization and filtration from phosphates receive 125 g of product (yield 93.5%) as a slightly yellowish flowing paste with a cloud point and chromaticity on an iodometric scale equal to 2. The composition of the product,%: polyoxyethylene glycol ether 65, acetal 35. Examples 3-15 of the preparation of TIA are presented in Table 1. Example 16 (comparative). Under the conditions of Example 1, of 118.7 g (0.2 g-mol) of alkylpolyoxyethylene glycol ether (, g-C ,,) and 4.0 g (0.04 g-mol) of vinyl-H-butyl ether (molar the ratio of the proportion of oxyethyleneglycol ether: vinyl ether 1: 0.2), 1.2 t (0.012 gmol) of orthophosphoric acid get 115.3 g (yield 94%) of a pasty, figurative substance of light yellow color with a cloud point, chromaticity 2 units on iodometric scale.

Example 17 (comparative). From 62.0 g (0.1 g-mol) of polyoxyethyleneglycol ethers of the alcohol fraction with the degree of oxyethylation of O 10, 9.5 g (0.09 g-mol) of vinyl isobutyl ether (molar ratio of polyoxyethylene glycol ether: vinyl ether 1: 0, 95) and 0.75 g of orthophosphoric acid gives 66.4 g (93% of the theoretical) of the product as a yellow viscous liquid.

ti, insoluble in water (cloud point is below 15 ° C), chromaticity is 10 units on an iodometric scale. The composition of the drug,%: polyoxyethylene- 5 glycol ether 8, acetal 92.

The TREs obtained by the proposed method are in appearance a slightly colored viscous substance, well soluble in water 10 and possessing a complex of adsorption properties: high wetting effect, low surface tension along with low foaming ability. Received by

Thus, with the ratio of alkylpolyoxyethyleneglycol ether: vinyl ether 1: 0.2, the surface tension is increased to 45 mN / m and, according to the proposed method, the preparation is a highly effective textile-auxiliary substance. The physicochemical properties that characterize the obtained TVB are given in Table 2 (temperature -, cloudiness is a measure of the solubility of the substance: at 20-25 ° C the substance does not dissolve or does not dissolve poorly, at 25 ° C it dissolves). As can be seen from the table. -2 The proposed method allows to obtain TVB with good (80-90%) detergent properties, low (2-4 on an iodine scale) chromaticity, good resistance to electrolytes. At the same time, the wetting ability (55-110 s) and the surface tension (32-38 mN / m) for TIA, obtained by the proposed method, are significantly better than for the synthanol DC-10 (120 and 44 mN / m, respectively) l and the same with TVB obtained by method 23 (does not wet, 45 mN / m), and therefore the positive effect of the invention achieved is not the cumulative effect of combining two known TBB. Conducting the process. conditions other than those proposed do not allow to achieve the goal. UP TO 120 s wetting ability. and foaming is increased (comparative example 16). When the ratio of alkylpolyoxyethylene glycol ether: vinyl ether is 1: 0.9 to 45 mN / m, the surface tension increases, the wetting ability disappears (comparative example 17).
