The invention provides compounds of the formula 1
in which
A is a C2- to C4-alkylene group
x is from 1 to 100
R1 is C1-C30-alkyl, C2-C30-alkenyl, C7-C30-alkylaryl
R2 is an aliphatic, cycloaliphatic or aromatic radical which contains at least one structural unit of the formula 2
and
y is from 0 to 100,
with the proviso that y is from 1 to 100 when R2 is of the formula 2, and their use in amounts of from 0.01 to 2% by weight for preventing the formation of gas hydrates in aqueous phases which are in contact with a gaseous, liquid or solid organic phase.
这项发明提供了以下式1的化合物
其中
A是一个C2到C4的烷基烯基
x为1至100
R1是C1-C30烷基,C2-C30烯基,C7-C30烷基芳基
R2是含有至少一个以下式2结构单元的脂肪、环脂肪或芳香基团
并且
y为0至100,
但要求当R2为式2时,y为1至100,并且它们在与气态、液态或固态有机相接触的水相中以0.01至2%的重量使用,以防止气体水合物的形成。
