preparation example Construction

[0013] The preparation method and process of the gasoline anti-violence standard-increasing agent of the present invention are as follows: 1. Weigh the raw materials according to the proportion and put them into the reactor; 2. Stir evenly and gradually heat up. When the temperature reaches 40 degrees, stop stirring and Heating, 3. After standing still for 1~2 hours, repack, and pay attention to fire prevention during the production process.

[0014] Raw material of the present invention and effect:

[0015] Methanol is a colorless, transparent, volatile liquid with a slight smell of ethanol, with a boiling point of 65C and a melting point of -97.8C. Methanol can be miscible with water in any ratio, but does not form an azeotrope. It can mix with most commonly used organic solvents.

[0016] Methyl tert-butyl ether is a colorless liquid. Slightly soluble in water, soluble in ethanol and ether. It can be used as a gasoline additive to replace tetraethyl lead and increase octa...

Embodiment 1

[0021] Weigh raw materials according to the following weights (based on the total weight of raw materials 1000KG):

[0022] 1. Methanol 200KG

[0023] 2. Methyl tert-butyl ether 500KG

[0024] 3. Methylcyclopentadienyl manganese tricarbonyl 300KG

[0025] Weigh the raw materials and put them into the reaction kettle, stir evenly and gradually heat up, stop stirring and heating when the temperature rises to 40 degrees, let it stand for 1-2 hours and then pack it.

Abstract

The invention relates to an antiknock additive for gasoline, with abundant raw material sources, low production cost, and simple manufacturing technique, which can effectively improve the octane rating, grades and combustion performance of the gasoline, and reduce the knock property of the gasoline. The antiknock additive for gasoline is mainly characterized by consisting of three types raw materials of methyl alcohol, methyl tert-butyl ether, and methylcyclopentadienyl manganese tricarbonyl. Due to the lead-free, nontoxicity and iron-base-free antiknock additive with low use level of methylcyclopentadienyl manganese tricarbonyl, shortcomings in the existing antiknock additive for gasoline are overcome. With little pollution, the application of the antiknock additive for gasoline can lead the No. 60 benzoline to be changed into environment-friendly gasoline as No. 90, 93 and 97.

Description

technical field [0001] The invention provides a gasoline additive for automobiles, in particular to an antiknock and mark-increasing agent. Background technique [0002] The octane number of gasoline is an important indicator that affects the stable combustion of automobiles, improves power and prolongs the service life of engines. In modern technology, in addition to using advanced refining processes (such as catalytic, cracking, reforming, hydrogenation, etc.) to produce high-octane gasoline, it is also used to add unleaded antiknock agents to gasoline with low octane to improve Octane, but expensive to produce, high in manganese, and radioactive. In 1959, the American ETHYL company invented an antiknock agent, which can effectively increase the octane number of gasoline, but during use, porous deposits are formed on the inner surface of the engine combustion chamber, which shortens the service life of the spark plug. In recent years, my country has also developed a vari...
