An overview,

In the process of blending oil, in order to reduce costs, many manufacturers will choose methylal as the raw material for blending oil, but the oil added with methylal has the following shortcomings in the use process:

1, not enough octane number, the octane number of methylal is only 76;

2. The vapor pressure is relatively large, and the boiling point of methylal is 42.3℃. When used in summer, it is easy to produce gas resistance, which seriously affects the normal use.

3, insufficient power, the oxygen content of methylal is 42.1%, in the process of oil mixing too much will make the oil oxygen content is too large, and oxygen in the combustion process only play a role in combustion, does not produce heat, so in the oil mixing these oxygen-containing substances will cause the calorific value of the oil decreased, oil consumption increased;

4. When emulsified with water, methylal is generated by dehydration of methanol and formaldehyde under the condition of catalyst, in which methanol is too much, so when methylal is mixed into oil, the water dissolution test can not pass.

Due to several reasons of methylal itself, a large proportion of methylal cannot be added directly in the oil blending process, and a small proportion of added oil cannot be used in the summer.

According to the above situation, Puyang Jiahua Chemical Co., Ltd. and Chinese Academy of Sciences have successfully developed a multi-functional modifier after years of research and practical trial, which has been verified in many oil mixing companies. It has the following functions:

1, inhibit the evaporation of oil, reduce the saturated vapor pressure of oil, prevent the generation of gas resistance, overcome the shortcomings of methylal can not be used in summer.

2, improve the combustion performance of methylal, improve the calorific value of methylal fuel, reduce the fuel consumption of blending fuel. The use of blending oil and the use of national standard oil fuel consumption. Multifunctional improver is also suitable for methanol gasoline and ethanol gasoline.

3. The octane value of the modifier itself is very high, and the octane value can reach more than 130. It can increase the anti-knock property of the oil and improve the brand of the oil when added to the oil.

4. Modifier can change the emulsification problem of methylal when it meets water, and solve the problem of water dissolution experiment.

The improverant has the function of cleaning and combustion support. It can be added to the oil to improve the cleanliness of the oil, keep the oil circuit and the nozzle clean, extend the service life of the nozzle, and promote the complete combustion of the oil, reduce the fuel consumption, and reduce the emission of harmful gases in the tail gas.

II. Technical indicators

Third, the method of reconciliation

 Add 10% (mass ratio) of modifier into gasoline and stir well.
