Application of 1-Bromobutane
For the preparation of butyl-terminated allyl polyoxyethylene ether
Butyl-terminated allyl polyoxyethylene ether has oil solubility, high temperature resistance, acid and alkali resistance, foam suppression, etc. All have improved capabilities and have unique features. Butyl-terminated allyl polyoxyethylene ether can be used not only in the oil for high-speed spinning of chemical fibers, but also as an additive in high-temperature-resistant lubricating oil or heat-conducting oil; it can also be used in strongly alkaline detergent formulations In addition, it is an excellent cell opener and silicone foam stabilizer in the polyurethane industry.
CN200910102019.6 provides a method for preparing butyl-terminated allyl polyoxyethylene ether. During the reaction process, water is removed as a by-product, so as to promote the sufficient reaction of polyether and alkali to generate alkoxide. The alkoxide and bromobutane are fully reacted in the autoclave to obtain the corresponding end-capped polyether, which has the advantages of fast reaction speed, no pollution and high end-capping efficiency.
In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme. As an alkoxide reagent, react with allyl polyoxyethylene ether to generate allyl polyoxyethylene alkoxide, and then react with bromobutane as an end capping agent to prepare butyl end capped allyl polyoxyethylene ether ; The alkoxide reagent adopts any one of solid potassium hydroxide or sodium hydroxide or a mixture thereof; and the molar ratio of allyl polyoxyethylene ether to the alkoxide reagent is 1: 1 to 1.5. In the present invention, bromobutane is reasonably selected as the end-capping agent, and the utilization rate is high.
For industrial production of tetrabutylphosphonium bromide
Tetrabutylphosphonium bromide belongs to the onium salt class of phase transfer catalysts. The object of the invention is to provide a new method for industrialized production of tetrabutylphosphonium bromide.
CN200610038424.2 provides a method for producing tetrabutylphosphonium bromide, using bromobutane, magnesium strips, phosphorus trichloride and tetrahydrofuran (solvent) as starting materials, firstly producing tributylphosphine, and then using tributylene Phosphine, bromobutane, and acetonitrile (solvent) were synthesized to obtain tetrabutylphosphonium bromide.
Compared with the prior art, the method has the advantages of easy access to raw materials, simple process, simple operation, less pollution discharge, high reaction yield, good product quality (content≥99%), and low production cost.
Preparation of 1-Bromobutane
The existing synthesis technology of bromobutane mainly includes n-butanol and sodium bromide sulfuric acid method, n-butanol and hydrobromic acid sulfuric acid method, n-butanol and hydrobromic acid solid acid catalysis method, n-butanol and bromine sulfurization method. and so on.
Hydrobromic acid and n-butanol react in the presence of a catalyst to produce 1-bromobutane. Since hydrobromic acid is a by-product of mass production of aryl bromide flame retardants, it is economically reasonable and has been a research hotspot in recent years. Sulfuric acid as a catalyst will produce a large amount of dilute sulfuric acid in the production process, and the post-processing is relatively troublesome; the solid acid catalysis method is easily affected by the failure of the catalyst, resulting in unstable product yield, and the complex synthesis and regeneration process of the catalyst affects the promotion of this process.
Method one
Chinese invention patent CN102826954 discloses a “preparation method of bromoalkane”, which is mixed according to the molar ratio of n-butanol and hydrobromic acid of 1:5, heated to a reflux state, and continuously and uniformly added dropwise and the gas outlet speed is adjusted to make the liquid The amount of dripping and the amount of steaming out are corresponding to keep the kettle liquid stable.
However, this method has a long reaction time, needs 6-12 hours, and has a large amount of hydrobromic acid and a low utilization rate.
Method two
Chinese invention patent CN102766013A discloses a “environmentally friendly method for preparing bromoalkane”. First, a certain amount of hydrobromic acid solution is preheated in a reactor until steam is generated, and the molar ratio of n-butanol and hydrobromic acid is 1 : 1 was mixed and added to the reactor, while raising the reaction temperature.
However, the reaction time of this method is still long, and it is a batch production, which cannot be continuously produced.
Method three
Chinese invention patent CN102875323B discloses a method for preparing bromo-tert-butane by brominating tert-butanol in a microchannel reactor. Using concentrated sulfuric acid as a catalyst, tert-butanol and hydrobromic acid are reacted in a micro-channel reactor to prepare tertiary bromide. Butanol.
However, this method still uses concentrated sulfuric acid, so it is necessary to deal with the problem of equipment corrosion caused by concentrated sulfuric acid and the problem of environmental pollution caused by waste acid.
Method four
Therefore, there is still a need to develop new processes for producing 1-bromobutane with high efficiency, high yield, high selectivity, low cost, low by-products, and no pollution. CN201810594072.1 provides a continuous process for preparing bromobutane in a microchannel reactor.
Compared with the existing process, the process has the advantages of precise control of reaction conditions, no catalyst, short reaction time, good selectivity, high yield, few by-products, high product purity, flexible, safe and efficient operation.
