Liquid dye for gasoline and preparation method thereof

Abstract

The invention provides a liquid dye for gasoline and a preparation method thereof. The liquid dye comprises the following components of: 25-35 percent of solvent type dye, 40-60 percent of varsol, 3-7 percent of auxiliary, 9-13 percent of antifreeze agent, and 3-5 percent of surfactant. The preparation method comprises the following steps of: adding the varsol, the auxiliary, the antifreeze agent and the surfactant into a stirring pot according to proportion, uniformly stirring, adding the required solvent type dye according to proportion, continuing stirring for 2 hours at normal temperature under normal pressure, filtering after the components are fully dissolved, discharging, and finally canning. A special solvent dye is adopted for the dye so as to ensure that the solubility of the solvent can reach 40-60 percent in the varsol, after the dye is added, the color is more attractive, the management is more convenient, the dissolution of the dye is uniform, and the residue and heavy metal contents are quite low, and after the dye is added into the gasoline, the original purity of the gasoline cannot be reduced, therefore, not only the quality of the original gasoline is guaranteed, the explosionproof property of a vehicle is not reduced and no damage is generated to a cylinder of a vehicle, but also the vehicle exhaust gas emitted are clean and has no pollution.

Description

technical field [0001] The invention relates to a liquid dye for gasoline and a preparation method thereof, belonging to the technical field of dyes. Background technique [0002] At present, the gasoline sold in the domestic market is all colorless gasoline, but due to some special needs in foreign markets, colored gasoline has begun to be used. Countries and regions such as the United States, Europe, and Hong Kong use different colors to distinguish different oil products and products. The use, grade quality, control purpose, etc. of the same specification oil make it have obvious characteristics, such as: because of tax reasons and safety reasons, aviation gasoline is colored. [0003] With the development of the times, my country's gasoline market will also move towards a colored era. To make gasoline colored, the dyes used for gasoline dyeing must first be solved. At present, the production and sales of domestic gasoline special dyes are still blank. Pure dyes are crys...

AI Technical Summary

Problems solved by technology

Pure dyes are crystalline particles. If they are used as dyes for gasoline dyeing, they need to have high solubility. Otherwise, the gasoline will become original due to factors such as insoluble particles, poor uniformity, and high residue heavy metal content. The reduction of the purity and the deterioration of the quality will inevitably seriously affect the cylinder of the car and cannot be used.
