Abstract
The invention discloses a process for synthesizing an emulsifying viscosity reducer for thick oil. The process comprises the steps: (a) carrying out a condensation reaction on octylphenol polyoxyethylene ether and formaldehyde; (b) carrying out a sulfonation reaction on copolycondensate and concentrated sulfuric acid; and (c) finally, carrying out neutralizing, thereby preparing the emulsifying viscosity reducer for the thick oil. According to the process, the emulsifying viscosity reducer for the thick oil can be successfully synthesized, the synthesis efficiency is high, and the cost required by synthesis is low; and through controlling condensation reaction time in a reaction process, the stability of the product is improved.
Description
Technical field
The invention belongs to technical field of chemical synthesis, it is specifically related to a kind of emulsifying and viscosity-reducing agent for condensed oil synthesis technique.
Background technology
Emulsifying pour depressor has to reduce sticks with paste viscosity, reduces plasticising dosage, reduces costs, and steady gluing waits effect. In the technological process method preparing emulsifying and viscosity-reducing agent for condensed oil at present, technical process is not easy to implement, and the emulsifying and viscosity-reducing agent for condensed oil finished product purity of generation is low, reactant per pass conversion is low, production process is complicated, and production efficiency is low and cost height, is not suitable for scale operation.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art exists, it is an object of the present invention to provide a kind of emulsifying and viscosity-reducing agent for condensed oil synthesis technique, the present invention not only production process simple, increase work efficiency, and the emulsifying and viscosity-reducing agent for condensed oil product purity generated is big, it is applicable to suitability for industrialized production.
The synthesis technique of emulsifying and viscosity-reducing agent for condensed oil synthesis technique provided by the invention, comprises the following steps:
First, (1) in reaction vessel, add polyoxyethylene octylphenol ether, it is warming up to certain temperature;
(2) then, add catalyzer, slowly drip and add formaldehyde, condensation reaction 4.5��6.5h;
(3) sulfonation reaction of co-condensation polymer and the vitriol oil;
(4) the obtained emulsifying and viscosity-reducing agent for condensed oil of finally neutralization.
Emulsifying and viscosity-reducing agent for condensed oil synthesis technique provided by the invention, its useful effect is, overcoming prior art, to prepare operation in emulsifying and viscosity-reducing agent for condensed oil synthesis process more, the problem that workload is big, it is to increase working efficiency; Improve the per pass conversion of reactant and the product rate of resultant.
Embodiment
Below in conjunction with an embodiment, emulsifying and viscosity-reducing agent for condensed oil synthesis technique provided by the invention is described in detail.
Embodiment
The emulsifying and viscosity-reducing agent for condensed oil synthesis technique of the present embodiment, comprises the following steps:
First, (1) in reaction vessel, add polyoxyethylene octylphenol ether, it is warming up to certain temperature;
