Abstract
The utility model relates to a gas-liquid reaction device for phenols and isobutene. The device comprises an autoclave, a condensing unit and a pressure measuring device. The utility model is characterized in that the device is also provided with a Venturi ejector and a circulating pump communicated with the liquid outlet on the lower portion of the autoclave. The Venturi ejector is arranged on the upper portion of the autoclave and communicated with the liquid in the autoclave by a connecting pipe and the circulating pump is communicated with the Venturi ejector by a connecting pipe. The autoclave, the circulating pump and the Venturi ejector are connected by connecting pipes to form into a closed circulation system. The pressure measuring device is arranged on the upper portion of the autoclave and communicated with the Venturi ejector, the autoclave and the condensing unit by a connecting pipe. The utility model has the advantages that the utility model is low in equipment investment, saves raw material and energy and greatly decreases production costs.
Description
Technical field
The utility model relates to a kind of gas-liquid reaction apparatus, the reaction unit of particularly a kind of phenols and iso-butylene.
Background technology
Tertiary butyl phenols is important organic synthesis raw material and the intermediate of a big class in the field of fine chemical, is widely used in to make medicine, auxiliary agent etc.Some tertiary butyl phenols self is exactly Chemicals such as anti-aging agent, oxidation inhibitor, stopper and stablizer, is indispensable additive in petroleum refining industry, petroleum chemical enterprise and the macromolecular material industry.
At present, two kinds of devices of the many employings of the reaction of phenols and iso-butylene, a kind of is simple gas liquid reaction still, the tail gas iso-butylene is collected or is diffused.Another kind is to adopt autoclave to make iso-butylene liquefaction, emission-free generation.All there is certain shortcoming in these two kinds of devices: though first kind of device equipment is simple, invest less, but because gas liquid reaction is inhomogeneous, produce a large amount of tail gas, need to collect discharging, contaminate environment, and the overwhelming majority of tail gas is to enter the isobutene gas that reactor does not have enough time to react, so just caused the huge waste on the raw material, the utilization ratio of iso-butylene is very low, certainly will increase the cost of product like this.Second kind of device adopts the liquefaction of autoclave iso-butylene, make the gas liquid reaction under the normal pressure under high pressure change into reactive liquid solution, react more even, emission-free generation, environmentally safe, iso-butylene does not have waste, has improved the utilization ratio of iso-butylene, has saved raw material, but adopt reaction under high pressure, equipment has particular requirement, and the facility investment height does not also have to reach the purpose of the cost that reduces product.China's tertiary butyl phenols production is in also that technology is outmoded, production cost is too high, can't satisfy the market stage.
Summary of the invention
Problems such as production cost height, the utilization ratio of raw materials that exists for the solution prior art is low, the purpose of this utility model provides a kind of phenols and isobutene reaction device, this device has increased venturi-type eductors and recycle pump on the basis of original reaction unit commonly used, make reaction more even, thorough, improved the iso-butylene rate, saved raw material, product cost is reduced greatly.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of phenols and isobutene reaction device, this device comprise reactor, condensing works, measuring stress device, it is characterized in that: this device also is provided with venturi-type eductors and recycle pump, and recycle pump is connected with reactor bottom liquid outlet; The Venturi spray tube is arranged on the top of reactor, by fluid connection in pipe connecting and the reactor; Recycle pump communicates with venturi-type eductors by pipe connecting; Reactor, recycle pump, Venturi spray tube link to each other by pipe connecting and have constituted a closed cycle system; The measuring stress device is located at reactor top, is connected with Venturi spray tube, reactor and condensing works by pipe connecting.
This device also is applicable to other gas-liquid reaction apparatus, uses this device to carry out other gas liquid reaction, all within the utility model protection domain.
The utility model has added venturi-type eductors and recycle pump on the basis of original reaction unit, reaction solution enters venturi-type eductors by recycle pump to be mixed in venturi-type eductors with isobutene gas, be ejected in the reactor by venturi-type eductors again, so reaction solution and isobutene gas constantly circulation in reactor makes reaction evenly, thoroughly.
Utilize this device when operating, earlier replace whole system with iso-butylene, open venturi-type eductors and recycle pump simultaneously, and the transport portion iso-butylene, treat by the measuring stress device, measure and be negative pressure in the still, illustrate that entering the interior isobutene gas of still reacts, import iso-butylene again, so circulation is till reaction finishes.
The utility model compared with prior art has following advantage: one, add recycle pump and venturi-type eductors, make liquid material and gas reaction more abundant, evenly; Two, do not produce tail gas in the entire reaction course, improve the utilization ratio of unstripped gas, shorten the reaction times, save energy consumption; Three, need not to add exhaust gas processing device, environmentally safe; Four, equipment is simple, the recycle pump of interpolation and venturi-type eductors low price, less investment.Carry out the gas liquid reaction test of phenols and iso-butylene according to the utility model, less investment on equipment, conservation and energy consumption, product cost reduces greatly.
