AI Technical Summary

Benefits of technology

The invention provides novel surfactants that do not have the disadvantages of traditional surfactants. These new surfactants can be used as adjuvants in agrochemical formulations, improving their effectiveness.

Problems solved by technology

The formulatability or gel formation may lead to massive problems with these surfactants, in particular in the process procedure of surfactant production or production of the formulation, and finally the result may be that the content of active substances and surfactants is relatively low.

experiment 1

According to the Invention

[0271]100 g of a mixture of saturated, linear C12- and C14-alcohols are initially introduced into a high-grade steel autoclave and 0.5% NaOH is added. Water is then stripped off at temperatures of from 130° C. to 180° C. 2 molar equivalents of ethylene oxide are then added and the reaction is carried out to give the corresponding fatty alcohol ethoxylate 3.1. The resulting product is reacted with ClSO3H (1.1 molar equivalents), while cooling. When the reaction has ended air is passed through the apparatus in order to remove hydrogen chloride. The resulting acid is slowly neutralized with dilute potassium hydroxide solution (2 N), while cooling. All the volatile components are then stripped off under a high vacuum. The residue can either be purified further (e.g. by a silica gel filtration with a polar, anhydrous solvent system, such as e.g. tetrahydrofuran, ethyl acetate or ethanol, and subsequent stripping off of the solvent under a high vacuum) or be empl...

experiment 2

According to the Invention

[0280]10 g of surfactant 1.1 (purity >90%) are dissolved together with 0.1 g of Acticide MBS (bactericide; Thor-Chemie) in 39.9 g of water. Depending on the purity of surfactant 1.1, an elevated temperature and intensive thorough mixing may be necessary for this. An adjuvant which comprises surfactant 1.1 in an amount of 20 percent by weight and can be employed directly for biological tests is obtained in this way.

experiment 3

According to the Invention

[0281]10 g of surfactant 1.1 are suspended with 30 g of glyphosate (acid) in 30 g of water, and 2 molar equivalents of pulverulent potassium hydroxide (2 molar equivalents with respect to glyphosate) are added, while cooling. The mixture is then topped up with water to a weight of 100 g.

[0282]An adjuvant-containing glyphosate formulation which comprises surfactant 1.1 is obtained in this way. This formulation can be used directly for biological tests.
