Problems solved by technology

However, because there are still some controversies about the use of MMT, the governments of various countries have adopted restrictive measures for the use of MMT, adding a limited amount to gasoline. Therefore, under the policy environment, the effect of MMT to increase the octane number of gasoline is limited ( 2-3 units)
On the other hand, as the amount of MMT increases, the increase in octane number of gasoline gradually decreases, and its advantages are gradually lost; and among the non-metallic antiknock agents currently produced, MTBE, which is commonly used in refineries, is added A large amount has a certain impact on the environment

Embodiment 1

[0020] A non-metal antiknock additive: comprising the following raw materials in parts by weight: 50 parts of N-methylformamide, 1 part of methyl tert-butyl ether, 2 parts of dimethyl carbonate, 5 parts of methyl p-hydroxybenzoate, glycerin hard 3 parts of fatty acid ester, 2 parts of inhibitor.

[0021] The inhibitor is polyethylene glycol, carboxymethyl cellulose, and limonene in a weight ratio of 1:0.2:0.1.

Embodiment 2

[0023] A non-metallic antiknock additive: comprising the following raw materials in parts by weight: 120 parts of N-methylformamide, 5 parts of methyl tert-butyl ether, 15 parts of dimethyl carbonate, 20 parts of methyl p-hydroxybenzoate, glycerin hard 18 parts of fatty acid ester, 8 parts of inhibitor.

[0024] The inhibitor is polyethylene glycol, carboxymethyl cellulose and limonene in a weight ratio of 3:0.9:0.6.

Embodiment 3

[0026] A non-metal antiknock additive, comprising the following raw materials in parts by weight: 80 parts of N-methylformamide, 3 parts of methyl tert-butyl ether, 8 parts of dimethyl carbonate, 12 parts of methyl p-hydroxybenzoate, glycerin hard 11 parts of fatty acid ester, 6 parts of inhibitor.

[0027] The inhibitor is polyethylene glycol, carboxymethyl cellulose, and limonene with a weight ratio of 2:0.5:0.4. The following preparation methods are used in the above-mentioned examples 1-3:

[0028] S1. Heat N-methylformamide, methyl tert-butyl ether, and dimethyl carbonate at 70°C for 40 minutes, heat-preserve and mix for 40 minutes, and then perform ultrasonic treatment at an ultrasonic frequency of 1600 MHz and a power of 700 W for 30 minutes to obtain material A;

[0029] S2. Add methyl p-hydroxybenzoate and glyceryl stearate into ethanol and soak at 50°C for 22 minutes, and then ultrasonically treat for 20 minutes at an ultrasonic frequency of 2000MHz and a power of 60...

Abstract

The invention provides a non-metal antiknock additive and a preparation method thereof. The antiknock additive comprises the following raw materials in parts by weight: 50-120 parts of N-methylformamide, 1-5 parts of methyl tert-butyl ether, 2-15 parts of dimethyl carbonate, 5-20 parts of methyl p-hydroxybenzoate, 3-18 parts of glyceryl stearate and 2-8 parts of an inhibitor. Preparation is carried out through the steps; gasoline blended by the obtained antiknock agent is good in stability, is not layered after being placed for two months, is not attenuated in octane number, does not change the original properties of the gasoline, can provide technical support for blending commercial gasoline by using a large amount of naphtha in oil refining gas and liquid, and can create more economic benefits for enterprises.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a non-metallic antiknock additive and a preparation method thereof. Background technique [0002] Since the advent of methylcyclopentadiene manganese tricarbonyl (MMT), as an antiknock agent with superior performance, it has been promoted and used in most countries in the world. However, because there are still some controversies about the use of MMT, the governments of various countries have adopted restrictive measures for the use of MMT, adding a limited amount to gasoline. Therefore, under the policy environment, the effect of MMT to increase the octane number of gasoline is limited ( 2-3 units). On the other hand, as the amount of MMT increases, the increase in octane number of gasoline gradually decreases, and its advantages are gradually lost; and among the non-metallic antiknock agents currently produced, MTBE, which is commonly used in refineries, is added A large...
