Paragraph 0022; 0023, (2017/07/19)
The invention discloses a hydroxylated ionic liquid type hydrate inhibitor of which a structural formula is shown in a formula I in the description. The hydrate inhibitor is prepared from N-ethoxy-N-methylpiperidine positive ions and negative ions at a molar ratio of 1 to 1. The inhibitor has the advantages of high electrical conductivity, good thermostability, small possibility of volatilization, biodegradability, no toxin, environmental friendliness and efficient inhibition performance. Under the low dose concentration of 0.5-3.0wt%, hydrate generation can be effectively inhibited, and reagent cost is greatly lowered; the hydroxylation ionic liquid hydrate inhibitor has wide applicability and wide application prospect, can be singly used and also can be subjected to inhibition mixing with commercial dynamics. (The formula I is shown in the description.), wherein R1 is a hydroxyethyl group, R2 is methyl, and X is C1 or Br.
