Due to oil bath generally use silicone oil, it is attached on behind reaction kettle outside it is difficult to clean, and silicone oil holds in cleaning process
Easily it is splashed into bottle, causes to pollute on a large scale, cleaning difficulty is larger, and relatively time-consuming, while can also cause silicone oil to waste, and improves
Experimental cost；Sand is usually put into electric heating cover during using sand-bath, since the diameter of electric heating cover is usually smaller, with reaction
The contact area of kettle is smaller, and experimenter's easy became uneven when being laid with sand, causes reaction kettle uneven heating even so that
Heat skewness in reaction kettle, and then the extent of reaction for influencing different zones differs, and causes reaction product purity poor.
The content of the invention
For defect existing in the prior art, it is an object of the invention to provide a kind of reaction for organic synthesis
Kettle, cleaning difficulty is smaller, and can reduce experimental cost.
To achieve the above objectives, the present invention adopts the technical scheme that：
A kind of reaction kettle for organic synthesis, including bottle, are provided with some sockets on the bottle, the bottle
Outside is provided with heating mantle, and the heating mantle includes coat part and heated portion, and the coat part cladding bottle outside is extremely
Few 2/3 area, the heated portion are fixed on the bottom of coat part, the heated portion be used to be in contact with heat source and incite somebody to action
Heat transfer is to coat part；It is provided with heat carrier between the coat part bottle, the thickness of the heat carrier is 4~8mm, institute
Stating coat part, thickness is sequentially increased from bottom to top, and the thermal conductivity of the heating mantle is more than 50W/M*K, the heat conduction of the heat carrier
Rate is more than 30W/M*K.
Further, the coat part is made of metal, and the heat carrier is made of ceramics.
Further, the outside of the coat part is coated with insulating layer.
Further, cooling body is plugged with the socket, the cooling body includes tube body, the inside of the tube body
Product pathways are provided with, the product pathways include high temperature channel and low temperature path, and the high temperature channel is helical pipe, described
Low temperature path is straight pipeline, and the length ratio of the high temperature channel and low temperature path is 1:0.5-2.
Further, it is cooling space between the tube wall of the product pathways and tube body, the cooling space is led to high temperature
The corresponding part in road is air setting portion, is water condensation portion with the corresponding part of low temperature path；
The air setting portion includes inner and outer tubes, and said inner tube is socketed on high temperature channel, and the outer tube is socketed in
In inner tube, the bottom of said inner tube is provided with air intake and air outlet slit, and the bottom of the outer tube is provided with condensing water inlet,
And outer tube is connected with water condensation portion by a condensation-water drain, for the water after cooling air to be imported in water condensation portion, institute
The top for stating water condensation portion is provided with water outlet.
Further, the length of the high temperature channel and low temperature path ratio is 1:0.8-1.5.
Further, the length of the high temperature channel and low temperature path ratio is 1:1.

Compared with prior art, the advantage of the invention is that：
(1) a kind of reaction kettle for organic synthesis in the present invention, by setting heating mantle in the exterior of bottle and leading
Hot body, wherein, heating mantle includes coat part and heated portion, and when in use, temperature as needed heats heated portion
Afterwards, temperature is transferred to heat carrier by coat part and heats bottle, since existing heating element is mostly embedded heating electric
Resistance, it is easy to damage, if being integrated in heating mantle, integral replacing is needed after damage, use cost can be increased, and added by outside
The mode of heat, can select the other modes such as water-bath, oil bath, since the thermal conductivity of heating mantle is higher, rapidly can pass temperature
Whole coat part is handed to, then passes to heat carrier again, although the thermal conductivity of heat carrier is relatively low, is their ability to delay bottle
Slow heating, avoiding temperature from raising suddenly causes bottle to burst, and when in use, only the heated portion of heating mantle connects with heat source
Touch, it is more convenient in cleaning, avoid the impurity such as the oil of heat source from being infected with to inside and outside bottle, reduce cleaning difficulty and use cost,
Improve conventional efficient.
(2) a kind of reaction kettle for organic synthesis in the present invention includes a cooling body, and air is from interior bottom of the tube
Air intake enters in inner tube, and the high-temperature product in high temperature channel is cooled down, meanwhile, the condensing water inlet in outer tube is beaten
Open, the air of inner tube is cooled down, and since the speed air flow in inner tube is very fast, air themperature will not excessively be dropped
It is low, air and high-temperature product excessive temperature differentials are avoided, causes pipe bursting；Meanwhile air preheats condensed water, it is heated
After condensed water afterwards enters water condensation portion by condensation-water drain, with convenient, the energy by the high-temperature gas temperature difference after air cooling
Enough avoid condensed water and high-temperature product excessive temperature differentials, cause pipe bursting, and can fast speed belt walk heat in high-temperature product.
(3) cooling body of the invention, since what is passed through in high-temperature pipe is high-temperature gas, will not occur product delay,
High-temperature pipe is caused to be difficult to situation about cleaning, and helical pipe can increase high-temperature gas and the direct contact surface in air setting portion
Product and time of contact, effectively high-temperature gas is cooled down, to reduce the temperature difference between high-temperature gas and condensed water, and low temperature leads to
Road uses straight pipeline, is adhered to after having product because of the relatively low liquefaction of temperature on straight pipeline, is also easier to clean, Neng Gouyou
Effect reduces the cleaning difficulty after experiment, saves experimental period.
(3) cooling body of the invention, in order to avoid the gas in cryogenic piping and condensed water excessive temperature differentials, leads in high temperature
One transition passage is set between road and low temperature path, and transition passage is spherical structure, and transition passage is opposite with air setting portion
Should, the length ratio of high temperature channel, transition passage and low temperature path is 1:0.5:2, under this condition, can to high-temperature gas into
Row fast cooling, and gas and condensed water excessive temperature differentials can be avoided to cause pipe explosion, the reaction time can not only be shortened, and
Compare safety.
