Description

Environmental-friendly methanol gasoline multifunctional synergist

Technical field

The present invention relates to a kind of gasoline dope, particularly relate to a kind of environmental-friendly methanol gasoline multifunctional synergist.

Background technology

Energy scarcity and environmental degradation have become the urgent recently problem that solves in the world, and gasoline is as the major impetus source of automobile, and except its price constantly increased, the discharging of CO also was one of factor that causes environmental degradation.At present, with methyl alcohol instead of part gasoline, with reach reduce cost and tail gas in the purpose of CO quantity discharged.But, increasing the compatibility of it and gasoline, and keep the use properties of former gasoline because the constructional feature of methanol molecules must add methanol gasoline additive.Chinese patent 101215484 discloses a kind of methanol gasoline additive, and component comprises methyl alcohol 25～30 in weight part, isopropylcarbinol 5～10, oleic acid 10～15, methylcarbonate 1～3, dme 1～3, tween 80 0.1～0.3, sorbester p17 0.1～0.3, methyl tertiary butyl ether 0.2～0.5, Methylal(dimethoxymethane) 0.1～0.3, acetone 1～2, the trimethyl carbinol 0.1～0.3, vulkacit H 0.1～0.3,102TB corrosion inhibitor 0.1～0.2.Because wherein surface-active emulsifiers such as tween 80 is a macromolecular compound, easy knot charcoal in pure oil, it is insufficient burn, and component is more, and cost is higher, and production technique is complexity, need carry out reacting by heating etc.

Summary of the invention

The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of cost low, production technique is simple, easy to use, good stability can reduce the comprehensive oily cost of using greatly, reduce the quantity discharged of CO in the tail gas, synergistic effect remarkable environmental type methanol gasoline multifunctional synergist.

Environmental-friendly methanol gasoline multifunctional synergist component of the present invention comprises by weight:

Methyl tertiary butyl ether 35～45,

Methyl-formiate 20～30,

Dimethylbenzene 20～30,

Alkyl Virahol 10～20,

The trimethyl carbinol 5～20,

Ferrocene 0.1～0.5,

Benzotriazole 0.05～0.1,

Dodecyl 2-ethylhexoate 0.5～1,

Trolamine 0.1.

Wherein, the alkyl Virahol is dodecyl Virahol or tetradecyl Virahol.The dodecyl 2-ethylhexoate has special effect, can form the cylinder film, increase to lubricate, and cleaning knot charcoal, strengthen power and oil-saving effect thereby reach.

The advantage of environmental-friendly methanol gasoline multifunctional synergist of the present invention is that this synergistic agent cost is low, starting material are easy to get, production technique is simple, synergistic effect is remarkable, easy to use, its power of the methanol gasoline that is mixed is suitable with No. 93 gasoline, and make the quantity discharged of CO in the tail gas reduce more than 90%, addition in methanol gasoline is generally 3～5% (volume ratios), it is good to add rear stability, methanol content can be shown in Table 1 up to 70% (volume ratio) in the methanol gasoline of preparation, uses oily comprehensive cost to descend more than 30%.Main as gasoline dope.

Embodiment

The cooperation ratio of the embodiment of the invention 1,2,3 is as follows by weight:

The component title	Embodiment 1	Embodiment 2	Embodiment 3
				Methyl tertiary butyl ether	??35	??37	??45
Methyl-formiate	??30	??22.5	??20
