AGROCHEMICAL ADJUVANTS AND COMPOSITIONS Russian patent published in 2017 - IPC C07D307/20 C07D309/10 A01N25/30 

FIELD: chemistry.

SUBSTANCE: invention relates to a mixture of compounds suitable as an adjuvant in agrochemical compositions, which are ethoxylated monoesters of fatty acid and sorbitan, in which the length of the fatty acid carbon chain is of 10 to 14 and the total degree of ethoxylation is of 8 to 12, where the esters are compounds of formula (I): Sorb-(EO_n1R¹) (EO_n2R²) (EO_n3R³) (EO_n4R⁴) (I), where Sorb represents a residue obtained by removing four hydroxyl H atoms from sorbitan; EO represents an ethyleneoxy residue; n1, n2, n3 and n4 are independent of 0 to 10; the sum of n1+ n2+3+ n4 is between 8 and 12; R¹, R², R³ and R⁴, each independently represents H or an acyl group -C (O) -R5, wherein R5 is alkyl of C10 to C14, where from 2.8 to 3.2 of R¹, R², R³ and R⁴ represent H, and where from 0.8 to 1.2 of R¹, R², R³ and R⁴ represent an acyl group -C(O)-R5.

EFFECT: new formulations reduce the antagonism of herbicidal compounds in agrochemical compositions.
