And influence product quality.
It is currently used the preparation method comprises the following steps: butyl titanate and isooctyl acid are put into reactor, and vacuumize；To vacuum degree
After stabilization, 50 degree are to slowly warm up to, is evaporated under reduced pressure 0.5 hour；It is warming up to 70 degree again, is evaporated under reduced pressure 0.5 hour；Finally it is warming up to
It 90 degree, is evaporated under reduced pressure 0.5 hour, reaction terminates.
The defect of aforesaid way is: vacuum distillation can be pumped into the vapor in air in kettle, cause butyl titanate
Hydrolysis, to influence product quality；In addition, esterification, while four fourth of metatitanic acid can occur with isooctyl acid for byproduct of reaction butanol
Ester can be used as catalyst for esterification reaction, accelerates esterification, also will affect product quality.
Therefore, how providing one kind can prevent raw material from hydrolyzing, and the air-breather for preventing side reaction from occurring, which becomes industry, to be needed
It solves the problems, such as.
Summary of the invention

Air-breather includes gas cylinder, air pump and vacuum pump；Isooctyl acid titanium preparation facilities between air pump and vacuum pump, and with air pump and
Vacuum pump is connected；Air pump is connected with gas cylinder.
The utility model can prevent raw material hydrolysis and side reaction from occurring in isooctyl acid titanium preparation process；It dispels simultaneously different
Butanol in sad titanium prevents it from corroding equipment during subsequent working process.
According to another specific embodiment of the utility model, isooctyl acid titanium preparation facilities includes:
Reaction kettle, reaction kettle are equipped with air inlet and exhaust outlet；Air inlet connects gas cylinder by air inlet pipe；

In the present solution, liquid butanol is stored in receiver bottom.
Isooctyl acid titanium is oily liquids, is stored in reactor bottom.
Need to guarantee in the butyl titanate finally obtained without containing butanol, otherwise butanol can it is subsequent in butyl titanate plus
Corrode plastic components in work treatment process, causes damages.
With isooctyl acid esterification can occur for butanol, while butyl titanate can be used as catalyst for esterification reaction；Under high temperature
Butanol gasification, can not be deposited in reaction kettle, can prevent side reaction.
According to another specific embodiment of the utility model, contain dry gas in gas cylinder；It can be prevented using dry gas
Tetrabutyl titanate hydrolysis.
According to another specific embodiment of the utility model, dry gas is dry air.
According to another specific embodiment of the utility model, dry gas is dry inert gas.
According to another specific embodiment of the utility model, reactor bottom is equipped with openable and closable material taking mouth；Reaction terminates
Afterwards, isooctyl acid titanium is discharged from material taking mouth.
According to another specific embodiment of the utility model, vacuum pump is connected with outside bleeding point；It is aspirated, is generated by vacuum pump
Negative pressure accelerates dry gas flowing, improves efficiency.
According to another specific embodiment of the utility model, reaction kettle is equipped with openable and closable feeding port；Feeding port is used for
Addition butyl titanate and isooctyl acid in reaction kettle.
According to another specific embodiment of the utility model, air inlet pipe is equipped with air pump；Dry gas is entered by air pump
Reaction kettle.
The operating method of the utility model is as follows:
1, butyl titanate is put into reaction kettle, the inventory of butyl titanate is 60-70g；It is past after feeding intake
Dry gas is passed through in reaction kettle；Dry gas enters reaction kettle from air inlet, leaves reaction kettle from exhaust outlet；Isooctyl acid titanium system
During standby, dry gas is in circulation status always；In reaction kettle in dry gas atmosphere；
2, reaction kettle under normal pressure, is directly heated 110-120 DEG C；Then isooctyl acid is added dropwise in reaction kettle, it is different pungent
The inventory of acid is 110-120g；Isooctyl acid reacts with butyl titanate, generates isooctyl acid titanium and butanol；
3, byproduct of reaction butanol gasifies at high temperature, under the extruding of dry gas, leaves reaction kettle from exhaust outlet；
4, gaseous state butanol enters receiver by connecting line with dry gas by liquefying after condenser；Dry gas
After condenser, receiver is entered by connecting line, and leave receiver from the bleeding point on receiver；When there is no liquid
When butanol enters receiver, reaction terminates.
Compared with prior art, the utility model have it is following the utility model has the advantages that
The utility model can prevent raw material hydrolysis and side reaction from occurring in isooctyl acid titanium preparation process；It dispels simultaneously different
