Embodiment 1

[0020] The gasoline detergent for vehicles is composed of methanol, octane and stabilizer; the stabilizer is composed of the following industrial raw materials in percentage by weight: 40% of N,N'-diphenylthiourea, 30% of polyethylene Amide, 20% dimethylglyoxime, 10% polymaleic anhydride. The car gasoline detergent composed of methanol, octane and stabilizer contains 30kg of octane and 4kg of stabilizer per 1000kg of methanol. And the vehicle gasoline detergent and gasoline are mixed and prepared according to the volume percentage of 30%, and after being blended with each other, they are directly added to the fuel tank and can be used directly.

[0021] The gasoline detergent for vehicles of this embodiment is prepared by the following steps:

[0022] Step 1. Add 4kg of stabilizer to 1000kg of methanol, and use pipelines and circulation pumps to carry out closed circulation and uniform stirring under normal temperature conditions;

[0023] Step 2. Add 30 kg of octane to the ...

Embodiment 2

[0025] The gasoline detergent for vehicles is composed of methanol, octane and stabilizer; the stabilizer is composed of the following industrial raw materials in percentage by weight: 40% of N,N'-diphenylthiourea, 40% of polyethylene Amide, 10% dimethylglyoxime, 10% polymaleic anhydride. The car gasoline detergent composed of methanol, octane and stabilizer contains 40kg of octane and 5kg of stabilizer per 1000kg of methanol. The vehicle gasoline detergent and gasoline are mixed and prepared according to the volume percentage of 35%, and are directly added to the fuel tank after being blended with each other, and can be used directly.

[0026] The gasoline detergent for vehicles of this embodiment is prepared by the following steps:

[0027] Step 1. Add 5kg of stabilizer to 1000kg of methanol, and use pipelines and circulation pumps to carry out closed circulation and uniform stirring under normal temperature conditions;

[0028] Step 2. Add 40 kg of octane to the mixed sol...

Embodiment 3

[0030] The gasoline detergent for vehicles is composed of methanol, octane and stabilizer; the stabilizer is composed of the following industrial raw materials in percentage by weight: 45% of N,N'-diphenylthiourea, 30% of polyethylene Amide, 10% dimethylglyoxime, 15% polymaleic anhydride. For every 1000kg of methanol in the automotive gasoline detergent composed of methanol, octane and stabilizer, it contains 30-100kg of octane and 4-5kg of stabilizer according to different grades of gasoline, according to different grades of gasoline, and according to the power performance of the vehicle. And the vehicle gasoline detergent and gasoline are mixed and prepared according to the volume percentage of 30-40%, and after being blended with each other, they are directly added into the fuel tank and can be used directly.

Abstract

The invention provides a vehicle gasoline detergent and a preparation method thereof. The vehicle gasoline detergent is prepared by the following steps: adding a stabilizer into methanol under uniformstirring at normal temperature, adding octyl hydrocarbon under uniform stirring, uniformly carrying out mixing, and then carrying out standing for 2 hours, wherein the stabilizer is composed of the following industrial raw materials in percentage by weight: 35-45% of N,N'-diphenylthiourea, 30-40% of polyvinyl amide, 10-20% of dimethylglyoxime and 8-15% of polymaleic anhydride. After the vehicle gasoline detergent is mixed with common gasoline, environment-friendly clean gasoline can be obtained, and intersolubility is ideal. After the vehicle gasoline detergent is mixed with the gasoline, thecontent of discharged harmful gas is low, power performance and cold start performance are ideal, heat resistance is avoided and carbon deposition is avoided. Meanwhile, the anti-explosion index of ordinary gasoline is effectively improved, and safety and reliability are achieved. In addition, corrosion of vehicle gasoline detergent to vehicle engines and other components is far less than corrosion of common gasoline, so that the vehicle gasoline detergent provided by the invention is a gasoline detergent with excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of petrochemical gasoline auxiliary additive preparations, and in particular relates to a vehicle gasoline detergent and a preparation method thereof. Background technique [0002] my country's gasoline is dominated by catalytic cracking gasoline, which has a relatively high olefin content and a relatively small alkylation content, which is prone to deposits, and the accumulation of gasoline deposits has a negative impact on the average life of the car and fuel consumption. Quality, usually need to add gasoline detergent. Under the prior art, gasoline detergents are generally composed of solvents, detergents, dispersants, antioxidants, and rust inhibitors, and are added to gasoline to mainly play the role of inhibiting and removing engine deposits. Under the prior art, the main problems when the gasoline detergent components are formulated and applied are as follows: firstly, the miscibility with ordinary ga...
