Embodiment 1

[0010] A kind of reaction still device that band intubation is produced butyl acrylate described in present embodiment 1, such as figure 1 As shown, it includes a reboiler 1, a reactor 2 connected to the reboiler and a bottom material pump 3 with a filter, and the reactor is connected to the bottom material pump; the reboiler is inserted through a reactor tube inserted into the reactor 4. Connect to the reactor; the bottom of the reactor insert is provided with a baffle 5 to cover the bottom port, and a cross-shaped opening 6 is provided on the bottom side of the reactor insert. The raw materials butanol and acrylic acid enter the reboiler for heating, then enter the bottom of the reactor, spray out to the reactor in a cross shape, and react with the catalyst in the reactor to form butyl acrylate; the reactor insert plays a stirring role and reduces Polymerization speeds up the reaction and reduces consumption; the baffle at the bottom of the intubation of the reactor can prev...

Abstract

The invention discloses a reaction kettle device with an inserted tube for producing butyl acrylate. The device comprises a reboiler, a reaction kettle connected with the reboiler, and a backing material pump with a filter, wherein the reaction kettle is connected with the backing material pump; the reboiler is connected with the reaction kettle by virtue of a reaction kettle insertion tube inserted into the reaction kettle; a baffle is arranged at the bottom of the reaction kettle insertion tube so as to cover the bottom opening; and a cross opening is formed in the side surface of the bottom of the reaction kettle insertion tube. The raw materials butanol and acrylic acid are heated in the eboiler, enter the bottom of the reaction kettle, are ejected to the reaction kettle in a cross shape and are contacted with a catalyst in the reaction kettle to react to generate the butyl acrylate; the reaction kettle insertion tube achieves a stirring effect, polymerization is reduced, the reaction is accelerated, and the consumption is reduced; and according to the baffle at the bottom of the reaction kettle insertion tube, the condition that gas directly rushes into the inlet of the bottoms pump so as to vacuumize the pump is avoided. According to the reaction kettle device, the problem that lots of butanol does not participate in the reaction because the original reaction kettle is incomplete in reaction is solved, and the structure is simple and practical.

Description

technical field [0001] The invention relates to the technical field of a reactor structure used in the chemical industry, in particular to a reactor device with an intubation tube for producing butyl acrylate. Background technique [0002] Butyl acrylate is an important organic chemical raw material, mainly used as organic synthesis intermediates, adhesives, emulsifiers, and coatings. It is widely used in industry. During use, butyl acrylate is often polymerized into polymers or copolymers. Butyl acrylate is a soft monomer, which can be copolymerized, cross-linked and grafted with various hard monomers to produce more than 200-700 kinds of acrylic resin products (mainly emulsion type, solvent type and water-soluble type), Widely used in coatings, adhesives, acrylic fiber modification, plastic modification, fiber and fabric processing, paper treatment agent, leather processing and acrylic rubber and many other aspects. [0003] At present, in the continuous production proc...
