Abstract

Przedmiotem wynalazku sa, majace zastosowanie, jako srodki chwastobójcze, nowe herbicydowe esterquaty z anionem halogenkowym o wzorze 1, w którym R1 oznacza podstawnik estrowy herbicydowy o wzorze 2, lub wzorze 3, lub wzorze 4, lub wzorze 5, lub wzorze 6, lub wzorze 7; R2 oznacza grupe alkilowa prostolancuchowa zawierajaca od 2 do 18 atomów wegla lub grupe alkoksymetylowa prostolancuchowa zawierajaca od 2 do 19 atomów wegla lub grupe cykloalkoksymetylowa zawierajaca od 5 do 13 atomów wegla; Xz ladunkiem ujemnym oznacza anion chlorkowy lub bromkowy lub jodkowy. Sposób ich otrzymywania polega na tym, ze ester deanolu, w którym czesc estrowa jest podstawnikiem herbicydowym o wzorze 2, lub wzorze 3, lub wzorze 4, lub wzorze 5, lub wzorze 6, lub wzorze 7, poddaje sie reakcji z halogenkiem alkilowym prostolancuchowym zawierajacym od 2 do 18 atomów wegla lub eterem chlorometylowoalkilowym z grupa alkoksymetylowa prostolancuchowa zawierajaca od 2 do 19 atomów wegla lub eterem chlorometylowocykloalkilowym z grupa cykloalkoksymetylowa zawierajaca od 5 do 13 atomów wegla w rozpuszczalniku polarnym, badz niepolarnym, dla halogenku alkilowego korzystnie w rozpuszczalniku polarnym - acetonie, a dla eteru chlorometylowoalkilowego i chlorometylowocykloalkilowego korzystnie w rozpuszczalniku niepolarnym - heksanie w stosunku molowym 1: (0,5 do 1,5), w temperaturze od 0 do 68°C, korzystnie w temperaturze pokojowej, po czym produkt w postaci czwartorzedowego halogenku esterquatu izoluje sie przez odsaczenie i przemycie heksanem lub calkowite odparowanie rozpuszczalnika i przemycie heksanem, a dalej suszy.The invention relates to novel herbicidal esterquats with a halide anion of formula I which are applicable as herbicides, wherein R 1 is a herbicidal ester substituent of formula 2, or formula 3, or formula 4, or formula 5, or formula 6, or formula 7; R2 is a straight chain alkyl group containing from 2 to 18 carbon atoms or a straight chain alkoxymethyl group containing from 2 to 19 carbon atoms or a cycloalkoxymethyl group containing from 5 to 13 carbon atoms; X with a negative charge means chloride or bromide or iodide anion. The method of their preparation is that the deanol ester in which the ester part is a herbicidal substituent of formula 2, or formula 3, or formula 4, or formula 5, or formula 6, or formula 7, is reacted with a straight chain alkyl halide containing from 2 to 18 carbon atoms or a chloromethylalkyl ether with a straight chain alkoxymethyl group containing from 2 to 19 carbon atoms or a chloromethylcycloalkyl ether with a cycloalkoxymethyl group containing from 5 to 13 carbon atoms in a polar or non-polar solvent, preferably with an alkyl halide solvent and for chloromethylalkyl and chloromethylcycloalkyl ether preferably in a non-polar solvent - hexane in a molar ratio of 1: (0.5 to 1.5) at a temperature of 0 to 68 ° C, preferably at room temperature, after which the esterquat quaternary halide product isolates by filtration and washing with hexane or complete evaporation solvent and washing with hexane, followed by drying.
