Abstract
The invention belongs to the field of gasoline additives and in particular relates to a gasoline antiknock. The main components of the gasoline antiknock are o-acetaminophenol, p-hydroxybenzenecarboxamide and 2-methylphenol in a weight ratio of 3:5:2. An antiknock experimental result shows that: when 3.0 to 5.0 percent of gasoline antiknock is added into the gasoline, the octane number of the gasoline can be improved and the antiknock performance is improved.
Description
Technical field
The invention belongs to the gasoline dope field, be specially a kind of gasoline antiknock composition.
Background technology
Existing theory is thought: gasoline by radical chain reaction mechanism burning, comprises the steps such as branching, chain termination of initiation, chain transmission, the chain of chain in cylinder.Pinking is the malcombustion phenomenon that the octane value of a kind of compression ratio when petrol motor and Fuel Petroleum occurs when not matching, the reason that produces pinking is: after gasoline/air Mixture igniting, along with the propagation in cylinder in the initial flame, unburned mixture is subjected to pressure and the hot effect that the burnt gas burning produces, oxidizing reaction strengthens, superoxide decomposes rapidly, the free radical branched chain reaction increases severely, spontaneous combustion had taken place and explosive combustion in the temperature of unburned mixture before the initial flame forward arrives, in cylinder, produce a plurality of combustion centre, each flame front is pushed ahead simultaneously, produces blast wave generation phenomenon of detonation.
The effect of gasoline antiknock is the automatic acceleration that suppresses combustion reactions, the combustionvelocity of gasoline is limited in the normal scope, namely before the forward of flame arrives, suppress the hydro carbons spontaneous combustion, the spontaneous combustion of unburned mixed gas is prolonged inductive phase, flame transmission speed is increased, reach the purpose of eliminating the fuel knock burning.
Enhancing along with people's environmental consciousness, the organic class octane promoter of metal of general leaded, manganese efficiently or iron because plumbous itself toxicity and the particulate matter that produces of other metal species compounds is polluted and to the harm of elements such as engine cylinder and exhaust system, be substituted gradually and stop using.
Octane promoter since the nineties in 20th century in the external reformulated gasoline that uses, also because of vapour lock, toxicity, antiknock efficient is low, synthesis technique is complicated, make the problems such as production cost increase of gasoline promote difficulty.
Therefore developing organic ashless class gasoline antiknock novel, efficient, cleaning is the urgent problem that current refining of petroleum industry both at home and abroad faces.
Summary of the invention
The present invention is the novel composition system that provides a class to can be used as gasoline antiknock on the basis of existing theory and technology.
Capability of antidetonance additivity rule according to the anti-knocking property group, select the compound of functional groups such as containing the higher phenyl of anti-knocking property, carboxyl, amido for use, carry out appropriate combination, it is good to obtain the capability of antidetonance, pollute for a short time, can make to substitute the gasoline antiknock of organo-metallic and complex compound class.
The main ingredient of gasoline antiknock of the present invention comprises adjacent acetaminophenol, a hydroxybenzene acid amides and 2-methylphenol.
The part by weight of the adjacent acetaminophenol of above-mentioned main ingredient, a hydroxybenzene acid amides and 2-methylphenol consumption is 3: 5: 2.
With the part by weight batching of said components in strict accordance with 3: 5: 2, mix according to the conventional working method of gasoline dope again, can make gasoline antiknock of the present invention.
Experimental result shows, adds octane promoter composition of the present invention in the gasoline, and the octane value of gasoline is improved, thereby has improved the capability of antidetonance of gasoline.Above-mentioned 3: 5: 2 part by weight is optimum material proportion, and the wherein minimizing of any amounts of components or increasing all can influence the capability of antidetonance of octane promoter composition.
The addition of gasoline antiknock composition of the present invention in gasoline is 3.0～5.0% volume parts.
The antiknock experimental result shows, adds gasoline antiknock of the present invention in the gasoline, and the octane value of gasoline is improved, and the capability of antidetonance strengthens.
The adjacent acetaminophenol of the component of gasoline antiknock of the present invention can be synthesized with acetic acid by o-amino phenol and makes, and building-up reactions is as follows:
Hydroxybenzene acid amides between the component of gasoline antiknock of the present invention can be made by m-Salicylic acid and ammonia synthesis, and building-up reactions is as follows:

Base oil is commercially available 90
#Motor spirit.
Experimental result is shown in table 1.As can be seen, this mixture.
Table 1 adds octane promoter of the present invention to the experimental result that influences of the gasoline capability of antidetonance
| Base oil | Gasoline antiknock | The gasoline antiknock volume fraction | Octane value |
| Commercially available 90 #Gasoline | 90.1 | ||
| Commercially available 90 #Gasoline | Prepared mixture | 3.0％ | 92.2 |
