Cost, make it production when effect it is more preferable.
Specific embodiment
A kind of new preparation method of long acting antibiotic material, it uses completely new production method, with traditional producer
Method is different, it is avoided in the prior art in such a way that expensive catalyst is produced, and thus greatly reduces
Production cost in production process, in the use process for making the later period of organosilicon quaternary ammonium salt long acting antibiotic material, use cost
It substantially reduces, its promotion effect in use can be made more preferable.Production method of the invention is not required in process of production
Excessive amine is removed using acid binding agent, make its in process of production more efficient, production process more simplifies, on the whole
Reduce production cost, keep its effect in production or use process all more preferable, this efficiently solve it is existing in the art
Production method is more complicated when production, controls relatively difficult technical problem, makes organosilicon quaternary ammonium salt long acting antibiotic material
Efficiency in production can greatly improve.The present invention includes: that 20.00g octadecyl 1) is added in three mouthfuls of reaction flasks
The step of dimethyl tertiary amine；This reaction flask tool there are three mouth is added, carry out using when it is more convenient, make it in process of production
Can reduce be added the substance occupied time, improve production efficiency in process of production.2) to the octadecyl of addition
Dimethyl tertiary amine carries out the step of uniform stirring；Ensure octadecyldimethyl tertiary amine dispersion it is more uniform, for it is subsequent and its
The substance that it is added carries out mixing and provides basis.3) 30.0g chloropropyl trimethyl is successively added into three mouthfuls of reaction flasks again
The step of silane and 50g propylene glycol monomethyl ether；4) nitrogen conveying dress is connected on one of input port of three mouthfuls of reaction flasks
It sets, it is ensured that the step of being completely under the protection of nitrogen in three mouthfuls of reaction flasks；Ensure them in subsequent heat reaction
Effect, enable the substance in three mouthfuls of reaction flasks heat reaction more sufficiently, and reaction efficiency is higher.5) to described three
Mouth reaction flask carries out carrying out the step of stirring and maintaining 35 hours after being heated to reflux；In this step, it is heated to reflux
Temperature is 120 degree or so under normal circumstances, it is ensured that sufficient reaction is able to carry out between each substance.6) it is cooled down, and
And the step of being cooled to room temperature.7) product after cooling is sampled, detects the product content of sampling, it is ensured that the content of product
Reach 80% or more step；Only reach the operation that this requirement just can be carried out next step.8) by three mouthfuls of reaction flasks
