Background technology
N- (4- carboethoxyphenyls)-N '-methyl-N '-phenyl formamidine is a kind of efficient uvioresistant additive, can
With the ultraviolet light of efficient absorption 240-340nm wave bands.Compared with the ultra-violet absorber of benzophenone or benzotriazole, N-
The anti-ultraviolet property of (4- carboethoxyphenyls)-N '-methyl-N '-phenyl formamidine is more excellent, thus with wide city
Field prospect.
The method for preparing N- (4- carboethoxyphenyls)-N '-methyl-N '-phenyl formamidine at present is with benzocainum
（Namely ethylaminobenzoate）For initiation material, passed through with trimethyl orthoformate/triethyl orthoformate and methylphenylamine
Two steps are condensed or step condensation is made reaction and is made.
The condensation of one step has the advantages that technique is simple, save equipment and energy consumption, production cost are relatively low, of reduced contamination, still
Do not know there are still following：（1）Typically carry out, be so easily caused pair in the absence of a solvent because a step is condensed
Benzocaine is deposited on bottom so that the reaction insufficient, reaction time is tediously long, and reaction temperature and Stress control are difficult
With free control, and then influence condensation reaction efficiency and yield；（2）The one step condensation ethanol amount of steaming is larger, is reclaimed for ethanol
The requirement of device is higher, and reaction efficiency is had a strong impact on if reclaiming not in time.
Utility model content
The purpose of this utility model is to solve the above problems, and there is provided a kind of N- (4- carboethoxyphenyls)-N '-first
Condensation reaction kettle is used in base-N '-phenyl formamidine production.
Realizing the technical scheme of the utility model purpose is：A kind of N- (4- carboethoxyphenyls)-N '-methyl-N '-benzene
Condensation reaction kettle, including kettle, electric stirring part, heater block, diversion component, dropper part and second are used in the production of base carbonamidine
Alcohol retracting device；The kettle is provided with ethylaminobenzoate charging aperture, triethyl orthoformate charging aperture, methylphenylamine
Charging aperture, ethanol reclaim outlet and discharging opening；The electric stirring part includes stirring motor, reductor, shaft coupling, stirring
Axle and paddle agitator；The heater block is heating coil；The diversion component includes being arranged on the inner wall of kettle
The distributing fin of two deflectors and one group of level being arranged on each deflector obliquely；Described two deflectors are relative
It is symmetrical arranged in the kettle axial line；The dropper part includes the primitive nail being arranged on the triethyl orthoformate charging aperture
Triethylenetetraminehexaacetic acid ester is added dropwise pipe, the methylphenylamine on the methylphenylamine charging aperture and pipe is added dropwise and institute is separately positioned on
State one group of dropwise addition hole that triethyl orthoformate is added dropwise on pipe and methylphenylamine dropwise addition pipe；The triethyl orthoformate is added dropwise
Pipe and the methylphenylamine are added dropwise pipe and are symmetrical arranged relative to the kettle axial line；The alcohol recovering device includes and institute
State ethanol and reclaim closed reception cylinder and the institute that outlet is connected by the cooler of pipeline connection, with the cooler by pipeline
State the closed reception cylinder surge tank connected by pipeline and the vavuum pump being connected with the surge tank by pipeline；It is described closed
Receive cylinder and be provided with vomit pipe.
Described two deflectors and the triethyl orthoformate are added dropwise pipe and the methylphenylamine be added dropwise pipe relative to
The kettle symmetrical chiasma is set, namely the plane where two deflector axial lines is vertically added dropwise where tube axis line with two
Plane.
The good effect that the utility model has：（1）Condensation reaction kettle of the present utility model is led by setting two to carry
The deflector of fin is flowed, so as to increase the contact area of reaction mass, the mixing severe degree of material is increased, makes bottoms material not
It can deposit, so as to improve reaction efficiency and reaction yield.（2）Condensation reaction kettle of the present utility model is by setting two with drop
Plus the dropwise addition pipe in hole, reaction mass is added from bottom is scattered in kettle so that reaction mass mixing evenly, it is rapider,
More fully, reaction efficiency and reaction yield are further improved.（3）Condensation reaction kettle of the present utility model is by setting ethanol to reclaim
Device makes material enter after being cooled down through subcooler in closed reception cylinder, so as to have the advantages that energy-saving, cost-effective, energy
It is enough to reclaim the ethanol distilled out in condensation reaction in time.
