Abstract
The invention discloses a preparation method of an active cleaning agent and belongs to the technical field of a fuel additive. The preparation method comprises the following steps of: (1) synthesizing isopropyl phosphate: pumping isopropanol into a reaction kettle; slowly adding phosphorus pentoxide in an agitating state; after adding materials, raising the temperature to 110-120 DEG C to react for 2-3 hours; reducing the temperature to be lower than 50 DEG C to obtain isopropyl phosphate; and (2) mixing: sequentially adding water, organic acid, alcohol, diethylene glycol and the isopropyl phosphate into a reaction kettle; agitating uniformly and dropwise adding organic amine; raising the temperature to 80 DEG C and preserving the heat for 2-4 hours; cooling down to be lower than 50 DEG C; pumping the materials into a storage groove; and standing for a week to obtain the cleaning agent. The preparation method is simple; and the prepared cleaning agent can be used as a preservative of circulated water, has de-scaling, dispersion and sterilization functions and has an inhibition rate which is more than or equal to 97%.
Description
Technical field
The invention belongs to the fuel oil additive technical field, be specifically related to a kind of preparation method of active purification agent.
Background technology
Automobile forms settling easily at positions such as carburettor, nozzle, intake valve, combustion chambers in the life-time service process, cause the motor car engine performance to reduce, and oil consumption increases, and exhaust emissions worsens, contaminate environment.For this reason, need in gasoline, add purification agent, remove or the minimizing engine deposits.As far back as the 1950's, people bring into use purification agent.Up to the present, people carry out large quantity research to each side such as the exploitation of purification agent, upgrading, method of evaluating performance, use propertieies, and develop four generation purification agent.China has promulgated motor spirit purification agent standard and corresponding use properties evaluation method.Purification agent in actual use, also needing to investigate purification agent affects rule to the clean-up performance of long-term deposit gasoline and ethanol petrol.
Purification agent is a kind of multi-effect composite additive that adds in the fuel, and it is by amino and phthalidyl polymeric surface active agent, the additive formations such as a small amount of antioxygen, anticorrosion, anti-rust metal deactivation, breakdown of emulsion.A kind of multi-effect composite additive that does not mainly make significant difference in order to clean fuel oil system, particularly carburettor, nozzle, intake valve and to the combustion chamber throw out.
Purification agent is the sanitising agent that can be attached on the dirt particle, and it can prevent that these particulates are adsorbed on the crucial surface, and sanitising agent also can be attached to metal surface itself, to keep cleaning surfaces and to prevent that corrosion from occuring.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of active purification agent.
