摘要:
This invention relates to a composition comprising:(1) polymer acids such as dimer or trimer acids and mixtures thereof, and(2) an alkyl succinic acid or the anhydride thereof, and the weight ratios of (1) to (2) being less than about 3 to 1; and to the use thereof as a corrosion inhibitor.Preferably the weight ratio of (1) to (2) is about 2 to 1 or less and the polymer acid is predominantly trimer acid.
摘要:
This invention relates to a process of inhibiting or preventing fouling (i.e., preventing the adhesion of deposits from hydrocarbon on surfaces) at elevated temperatures which comprises adding to hydrocarbon an antifouling (preventing) amount of an organo-sulfur compounds having a high sulfur content. In the preferred embodiment, the organo-sulfur compound has at least 5% sulfur. An embodiment is a heterocyclic compound, a dithiole-thione. These organo sulfur compounds are particularly effective at elevated temperatures of at least about 500.degree. F.
摘要:
A process of inhibiting corrosion and/or sweetening hydrocarbons so that they pass the Copper Strip Tarnish Test ASTM D-130 which comprises treating such hydrocarbons with iodine or bromine. These halogens are preferably employed with complexing compounds such as amines, carboxylic acids, alcohols, alkanolamines, ketones, etc.
摘要:
This invention relates to the reaction products of(1) an alkenyl or alkyl succinic acid or the anhydride thereof; and(2) an alkylether diamine; and to the use thereof as a corrosion inhibitor.
摘要:
This invention relates to a composition comprising(1) an alkenyl or alkyl succinic acid or the anhydride thereof; and(2) a triester of about 3 moles of an alkenyl or alkyl succinic acid or the anhydride thereof and about 1 mole of a trialkanolamine;and to the use thereof as a corrosion inhibitor.
