    • The present invention is an organopolysiloxane compound having at least one group having the formula
      and at least one group having its formula selected from -R 3 -C 6 H 5 or -R 3 -O-C 6 H 5 per molecule, wherein R 3 is a divalent hydrocarbon group having from 1 to 20 carbon atoms, R 4 is hydrogen atom, an alkyl group, an aryl group or an acyl group, d has a value of 0 to 150, e has a value of 0 to 150, with the proviso that the value of d+e is at least one. These compounds reduce the amount of foam in hydrocarbon fuels, especially in diesel and jet fuels. Our organopolysiloxane compound functions as a foam control agent that displays consistent compatibility and miscibility with additives which are frequently present in hydrocarbon fuels.
    • 本发明是具有至少一个具有下式的基团和至少一个具有选自-R 3 -C 6 H 5或-R 3 -OC 6 H 5的分子的每个分子的至少一个基团的有机聚硅氧烷化合物,其中R 3为具有1至2个碳原子的二价烃基, 20个碳原子,R 4为氢原子,烷基,芳基或酰基,d的值为0-150,e的值为0-150,条件是d + e的值为 最后一个。 这些化合物减少了碳氢燃料中的泡沫量,特别是在柴油和喷气燃料中。 我们的有机聚硅氧烷复合物起到泡沫控制剂的作用,与碳氢燃料中经常存在的添加剂显示出一致的相容性和混溶性。
