Study of 2 butoxyethanol effect on the inhibitor performance of N acryloylpyrrolidine and N vinyllactam high molecular compounds during gas hydrate formation
Effect of the 2-butoxyethanol on inhibitor performance of synthesized high-molecular compounds (HMC) during gas hydrate formation was investigated. HMC are homopolymers and copolymers of N-acryloylpyrrolidine, N-vinylpyrrolidone and N-vinylcaprolactam. It is found that the previously discovered synergetic effect of increasing the inhibitor performance of N-vinylcaprolactam HMC in the presence of 2-butoxyethanol is also appeared for N-acryloylpyrrolidine HMC. At most, this effect appears to binary copolymer of N-acryloyl-pyrrolidine and N-vinylpyrrolidone with the molar ratio of monomeric units 3:2.
