Abstract
The invention discloses a methanol gasoline corrosion inhibitor. The methanol gasoline corrosion inhibitor comprises the following components by mass: 18 to 25% of methanol, 10 to 20% of sodium hydroxide, 10 to 20% of benzotriazol, 5 to 12% of polyethylenediamine, 25 to 35% of n-butanol and 2 to 10% of polyvinylpyrrolidone. The above-mentioned components are uniformly mixed under full stirring so as to obtain the methanol gasoline corrosion inhibitor. Compared with the prior art, the invention has the following advantages: the methanol gasoline corrosion inhibitor has good corrosion inhibition effects on copper, iron and aluminum, is capable of adjusting the content of organic acid in methanol, forms a protection film on metal surface and can effectively alleviate rubber swelling caused by methanol; and through addition of 1% of the methanol gasoline corrosion inhibitor into methanol gasoline, methanol has corrosivity lower than first-grade copper corrosion and has a pH value of 7.4, completely meeting standards of national standard gasoline in China.
Description
Technical field
The present invention relates to gasoline dope field, particularly a kind of methanol gasoline inhibiter.
Background technology
Methanol gasoline is that vehicle fuel substitutes, and is the important component part of new forms of energy.Crude oil is global topmost primary energy source, and the essence of current energy source shortage is crude oil shortage.Vehicle fuel is the topmost Application Areas of crude oil, accounts for more than 70% of global crude oil total flow.Methanol gasoline is a kind of " replace oil with coal " path, can as the surrogate of gasoline thus the Some substitute realized crude oil.
But owing to adding methyl alcohol in methanol gasoline, the rubber components of methyl alcohol meeting in the oil circuit of automobile causes corrosion, and formaldehyde has corrosive nature to basic metal, and life-time service methanol gasoline can make the unnecessary loss of car to automobile simultaneously.
Therefore, a kind of methanol gasoline inhibiter is urgently developed.
Summary of the invention
The object of the invention is to provide a kind of formula simple, effectively can reduce corrosive methanol gasoline inhibiter.
For achieving the above object, the present invention implements according to following technical scheme:
A kind of methanol gasoline inhibiter, be made up of the component of following mass percent: methyl alcohol 18-25%, sodium hydroxide 10-20%, benzotriazole 10-20%, polyethyene diamine 5-12%, propyl carbinol 25-35%, polyvinylpyrrolidone 2-10%, above-mentioned each component is fully uniformly mixed and obtains methanol gasoline inhibiter.
As preferably, described methanol gasoline inhibiter is made up of the component of following mass percent: methyl alcohol 20%, sodium hydroxide 15%, benzotriazole 15%, polyethyene diamine 10%, propyl carbinol 30%, polyvinylpyrrolidone 10%.
Compared with prior art; the present invention has good corrosion inhibition to copper, iron, aluminium; there is the function of the organic acid content regulated in methyl alcohol; protective membrane is formed in metallic surface; and effectively can alleviate swelling to rubber of methyl alcohol, in methanol gasoline, add this additive of 1%, make the corrodibility of methanol gasoline reach copper corrosion less than 1 degree completely; pH value reaches 7.4, meets GB gasoline standard completely.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described, is used for explaining the present invention in this illustrative examples of inventing and explanation, but not as a limitation of the invention.
Embodiment 1
A kind of methanol gasoline inhibiter, be made up of the component of following mass percent: methyl alcohol 20%, sodium hydroxide 15%, benzotriazole 15%, polyethyene diamine 10%, propyl carbinol 30%, polyvinylpyrrolidone 10%, above-mentioned each component is fully uniformly mixed and obtains methanol gasoline inhibiter.
Embodiment 2
A kind of methanol gasoline inhibiter, be made up of the component of following mass percent: methyl alcohol 18%, sodium hydroxide 20%, benzotriazole 12%, polyethyene diamine 6%, propyl carbinol 34%, polyvinylpyrrolidone 10%, above-mentioned each component is fully uniformly mixed and obtains methanol gasoline inhibiter.
Embodiment 3
A kind of methanol gasoline inhibiter, be made up of the component of following mass percent: methyl alcohol 25%, sodium hydroxide 15%, benzotriazole 15%, polyethyene diamine 8%, propyl carbinol 32%, polyvinylpyrrolidone 5%, above-mentioned each component is fully uniformly mixed and obtains methanol gasoline inhibiter.
Summary, methanol gasoline inhibiter of the present invention by methyl alcohol 20%, sodium hydroxide 15%, benzotriazole 15%, polyethyene diamine 10%, propyl carbinol 30%, that polyvinylpyrrolidone 10% forms effect is best.Good corrosion inhibition is had to copper, iron, aluminium; there is the function of the organic acid content regulated in methyl alcohol; protective membrane is formed in metallic surface; and effectively can alleviate swelling to rubber of methyl alcohol; this additive of 1% is added in methanol gasoline; make the corrodibility of methanol gasoline reach copper corrosion less than 1 degree completely, pH value reaches 7.4, meets GB gasoline standard completely.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
