Abstract

The invention discloses polyether amine, a production method thereof, and application of the polyether amine in methanol gasoline. The polyether amine can improve intersolubility, water resistance, air resistance, acid-neutralizing capacity of the methanol gasoline simultaneously and simplify an additive formula and the production process of the methanol gasoline. The polyether amine is prepared by addition of hexylamine and ethylene oxide. Experiments prove that: when the polyether amine is used together with butanol or octanol which accounts for 2 to 3 percent of the total weight, the water resistance of the methanol gasoline is 1 to 2 percent, and when the polyether amine is used together with No.200 solvent oil or C9 aromatic hydrocarbon which accounts for 7 to 8 percent of the total weight, the saturated vapor pressure is less than 65kPa, and the methanol gasoline has the advantages of acid-neutralizing capacity and obvious improvement of a plurality of indexes. Due to the application of the polyether amine, the invention provides a method for producing the methanol gasoline, which has the advantages of simpleness, convenience, high efficiency and lower cost.

Description

technical field [0001] The present invention relates to a kind of polyetheramine and its production method and the application of the polyetheramine prepared by said method in methanol gasoline, especially relate to the method that this polyetheramine simplifies the additive formulation and production process of methanol gasoline, The invention also relates to a method for improving multiple indexes of methanol gasoline. Background technique [0002] In the methanol gasoline technology, the development status of the existing technologies is as follows: [0003] 1. Miscibility and water resistance [0004] With regard to realizing miscible water resistance, many known oxygen-containing compounds, such as the composition of ethers, higher alcohols, ketones and esters, can play an effective role. Patents offer some options for this. [0005] Commonly used co-solvents are C 3 ~C 8 Alcohols, which have hydroxyl groups (OH), can form hydrogen bonds with methanol, and have hyd...
