Abstract
The present invention discloses a heavy oil emulsifying viscosity reducer synthesis process based on sulfonation degree control. The heavy oil emulsifying viscosity reducer synthesis process comprises: (1) carrying out a condensation reaction of octyl phenol polyoxyethylene ether and formaldehyde; (b) carrying out a sulfonation reaction of a co-polycondensate and concentrated sulfuric acid, and controlling the sulfonation degree during the reaction process at 0.70-0.95; and (c) neutralizing to prepare the heavy oil emulsifying viscosity reducer. According to the present invention, the heavy oil emulsifying viscosity reducer is successfully synthesized, the synthesis efficiency is high, the synthesis cost is low, and by controlling the sulfonation degree during the reaction process, the product stability is improved.
Description
Technical field
The invention belongs to technical field of chemical synthesis, be specifically related to a kind of based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree.
Background technology
The kind of thinner is a lot. Wherein, the effect of polyethers thinner is better. ME drops withered dose can play the role that (1) reduces paste viscosity, and every 100 parts of PVC paste resins add 1 portion of ME thinner, can make paste decrease in viscosity 1/3 ~ 1/2. To high-speed coating, slush moulding, dip in mould, impregnating needs the moulding process of low viscosity PVC paste, adding thinner is effective viscosity reducing process. (2) reduce plasticising dosage for reduce stick with paste viscosity effect, 1 portion of ME thinner function as 6 one 8 parts of DOP. Therefore, for needing the product of higher hardness, thinner can be added to reduce plasticising dosage, make Article Stiffness Determination improve. In current emulsifying pour depressor building-up process method, technological process is not easy to implement, and the emulsifying and viscosity-reducing agent for condensed oil finished product purity of generation is low, and reactant conversion per pass is low, and manufacturing process is complicated, and production efficiency is low and cost high, is not suitable for large-scale production.
Summary of the invention
For the above-mentioned technical problem overcoming prior art to exist, it is an object of the invention to, there is provided a kind of based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree, the present invention not only manufacturing process is simple, improve work efficiency, and the emulsifying and viscosity-reducing agent for condensed oil product purity generated is greatly, is suitable for industrialized production.
Provided by the invention based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree, comprise the following steps:
(1) condensation reaction of OPEO and formaldehyde;
(2) sulfonating reaction of co-condensation polymer and concentrated sulphuric acid, and the sulfonation degree controlled in course of reaction is 0.70��0.95;
(3) prepared emulsifying and viscosity-reducing agent for condensed oil is finally neutralized.
Provided by the invention based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree, it has the beneficial effects that, overcoming prior art, to prepare operation in emulsifying and viscosity-reducing agent for condensed oil technical process more, and the problem that workload is big improves work efficiency; Improve the conversion per pass of reactant and the productivity of product.
Detailed description of the invention
Below in conjunction with an embodiment, it is described in detail based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree provided by the invention.
Embodiment
The emulsifying and viscosity-reducing agent for condensed oil synthesis technique based on control sulfonation degree of the present embodiment, comprises the following steps:
(1) condensation reaction of OPEO and formaldehyde;
(2) sulfonating reaction of co-condensation polymer and concentrated sulphuric acid, and the sulfonation degree controlled in course of reaction is 0.95;
(3) prepared emulsifying and viscosity-reducing agent for condensed oil is finally neutralized.
Based on the emulsifying and viscosity-reducing agent for condensed oil synthesis technique controlling sulfonation degree, it is not necessary to loaded down with trivial details post-reaction treatment, operation simple possible, and also environmentally friendly pollution-free, technological process is easy to implement, and production cost is low, synthesis yield is high, it is achieved that the industrialized production of product.
