Description
Technical field
The utility model is related to field of fine chemical, and in particular to a kind of serialization prepares the oxidation of fatty alkyl amido propyl
The device of amine.
Background technology
Fatty alkyl LAO (CAO) has the effects such as excellent bubble, cleaning, emulsification, solubilising, thickening, to oxidation
Agent, soda acid chemical stability preferably, it is gentle to skin and eyes, have cooperative effect, environmental protection, security with anion active agent
Also preferably, it is widely used in detergent, shampoo and fabric softener and shampoo.
Existing conventional CAO production technology, is usually to utilize fatty acid amide propyl tertiary amine (PKO) in a kettle. and double
Oxygen water reacts, in order to improve conversion ratio during production, need to increase the rate of charge of hydrogen peroxide, and must divide for the excessive kettle hydrogen peroxide of anti-material
Criticize and feed intake, add the reaction time, and because the excess of hydrogen peroxide, when causing to add the hydrogen peroxide residue degraded in finished product
Between.
Utility model content
The utility model purpose be to provide a kind of serialization prepare the device of fatty alkyl LAO there is provided
Device, which has, configures simple, the low feature of cost of investment.
The utility model provide technical scheme be：
A kind of continuous device for preparing fatty alkyl LAO, it is characterised in that the device is using pipeline
Liquid material entrance, static mixer, fixed bed reactors, gas-liquid separator, gas buffer tank and the blower fan being sequentially connected；
The liquid material entrance by passing through the PKO entrances of pipeline parallel connection access, dioxygen water inlet, distillation water inlet group respectively
Into；
The static mixer outlet is connected a reactor lower end import by pipeline.
The liquid outlet of the gas-liquid separator directly exports liquid product.
The gas buffer tank is provided with gaseous oxidant entrance, and the outlet of gas buffer tank provided with Air fan pipeline by connecting
Connect the import of fixed bed reactors lower end.
The utility model compared with the prior art, with advantages below：
1) the utility model uses continuous production technology, and it is small that the reaction time was reduced to 1~2 from traditional 5~6 hours
When, substantially increase production efficiency.
2) the utility model is used as oxidant by the use of ozone, hydrogen peroxide, it is to avoid the excessive hydrogen peroxide that common process needs,
The decomposition of hydrogen peroxide is reduced, cost is greatly reduced.
3) process units that the utility model is provided all is formed using existing apparatus configuration, and cost simple in construction is relatively low；
The utility model can also realize Automated condtrol, so as to improve product quality and ensure the stability of product quality.

Enter fixed bed reactors；It is 0.15Mpa that Maximum Concentration of Ozone is maintained in gas cushion, at the same ozone with 15kg/h flow velocity by blower fan
Deliver into fixed bed reactors.
Fixed bed reactors maintenance reaction temperature is 75 DEG C, the reaction product come out from fixed bed reactors, via gas-liquid
After separation, gas-phase product is collected in gas buffer tank, is continued as gaseous oxidant to reuse, and liquid product is
Target product-concentration is 31.5% fatty alkyl LAO (CAO), and it is 99.5% to measure conversion ratio.
Embodiment 2
In effective volume 1.5M3Fixed bed reactors in add 3000 grams of loading type silver catalyst.
(weight of material compares 3 for PKO, 30% hydrogen peroxide, distilled water:1:6) with 1000kg/h by entering after static mixer
Fixed bed reactors；Maximum Concentration of Ozone is maintained to be 0.2Mpa in gas cushion, while ozone is defeated by blower fan with 10kg/h flow velocity
It is fed into fixed bed reactors.
Fixed bed reactors maintenance reaction temperature is 70 DEG C, the reaction product come out from fixed bed reactors, via gas-liquid
After separation, gas-phase product is collected in gas buffer tank, is continued as gaseous oxidant to reuse, and liquid product is
Target product-concentration is 31.5% fatty alkyl LAO (CAO), and it is 99.5% to measure conversion ratio.
