Embodiment 1

[0011] Example 1: Take 1,000 liters of industrial methanol that complies with GB / T338----1992, add 0.5 liters of liquid dimethyl ether below the boiling point of dimethyl ether -24.9°C, and ignite smoothly at 0°C; Add the alkyl phosphate amine salt solution, adjust the pH value to 7 and stop adding, and it will have a significant antiseptic effect; add a saturated solution of sodium acetate at room temperature 0.5×10 -6 It can make the flame clear yellow; since the alkyl phosphate amine salt has been added, the amine smell of the feed liquid has covered the smell of ethanol, which can prevent people from drinking it by mistake, so there is no need to add other odor regulators.

Embodiment 2

[0012] Example 2: Take 1000 liters of industrial methanol in accordance with GB / T338----1992, add 100 liters of ether at room temperature to ignite smoothly; add alkyl phosphate amine salt solution at room temperature, adjust the pH value to 8 and stop Adding it can have a significant antiseptic effect; add a saturated solution of sodium ethidate at room temperature 10×10 -6 It can make the flame clear yellow; since the alkyl phosphate amine salt has been added, the amine smell of the feed liquid has covered the smell of ethanol, which can prevent people from drinking it by mistake, so there is no need to add other odor regulators.

Embodiment 3

[0013] Example 3: Take 1,000 liters of industrial methanol in accordance with GB / T338----1992, add 5 liters of liquid dimethyl ether below the boiling point of dimethyl ether -24.9°C, and ignite smoothly at 0°C; Add the alkyl phosphate amine salt solution, adjust the pH value to 7 and stop adding, and it will have a significant antiseptic effect; add a saturated solution of sodium acetate at room temperature 0.5×10 -6 It can make the flame clear yellow; since the alkyl phosphate amine salt has been added, the amine smell of the feed liquid has covered the smell of ethanol, which can prevent people from drinking it by mistake, so there is no need to add other odor regulators.

Abstract

The present invention relates to a kind of alcohol base civil fuel with crude methanol as main material and aid and its preparation process. The technological scheme is that into industrial methanol in 100 weight portions, ignition promoter in 0.05-10 weight portions, corrosion inhibitor in such amount as to reach the material liquid pH 7-8, and saturated sodium EDTA solution in (0íñ05í½1)í‡10< -6 > weight portions are added. The ignition promoter is ether, such as methyl ether and ethyl ether, or light oil; and the corrosion inhibitor is slight alkali corrosion inhibitor amino alkyl phosphate or aliphatic amine. The present invention has the advantages of high efficiency, saving in energy, environment friendship, safety, reliability and convenient operation.

Description

Technical field [0001] The invention relates to an alcohol-based civil fuel with additives prepared mainly from crude methanol and its preparation method. According to the industry standard NY311----1997 for alcohol-based civil fuel promulgated by the Ministry of Agriculture of my country, it is a kind of " "Alcohol-based civil fuels prepared mainly from crude methanol", which is similar to the national standard GB16663----1996 "Alcohol-based liquid fuels". When they are used as civil cooking fuels, some ignition accelerators and corrosion inhibitors should be added. enhancer, flame colorant and odor regulator to help it work better. Background technique [0002] When alcohol-based civil fuel is used as civil cooking fuel, some performance improvers should be added: one is ignition accelerator, because its vapor pressure is relatively low, it is sometimes difficult to use modern electric ignition, so it needs to be added appropriately Some ignition accelerators; the second is...
