Linear alkylsilicone compounds of the formula
wherein x = 0 to 20, preferably 0 to 10, most preferably 0 to 1; y = 1 to 10, preferably 1 to 5, most preferably 1; and R is an alkyl or alkyl ester group containing 6 to 16 carbons, or cyclic alkylsilicone compounds of the formula
where m is 0 to 4, preferably 0 to 2, most preferably 0,
and n is 1 to 5, preferably 3 to 5, most preferably 4,
provided that m + n = 3 to 5 ,
are adjuvants for agricultural applications of oil-containing compositions. Especially preferred alkylsilicone compounds have a degree of polymerization of ≦ 6 and an alkyl content of ≦ 50% by weight. The compounds potentiate spreading of mineral or vegetable oils or oil-containing emulsions in dormant spray oils, crop oil concentrates, pesticides, and the like on difficult-to wet surfaces such as waxy leaf cuticles and arthropod exoskeletons.
式中的线性烷基硅化合物
其中 x = 0 至 20,优选 0 至 10,最优选 0 至 1;y = 1 至 10,优选 1 至 5,最优选 1;以及 R 是含有 6 至 16 个碳原子的烷基或烷基酯基团,或式中的环状烷基硅化合物
其中 m 是 0 至 4,最好是 0 至 2,最理想是 0、
n 为 1 至 5,优选 3 至 5,最优选 4、
条件是 m + n = 3 至 5、
是含油组合物农业应用的佐剂。特别优选的烷基硅化合物的聚合度为 ≦ 6,烷基含量为 ≦ 50%(按重量计)。这种化合物可促进矿物油或植物油或休眠喷雾油、作物浓缩油、杀虫剂等含油乳液在蜡质叶片角质层和节肢动物外骨骼等难以润湿表面上的铺展。
