Problems solved by technology
[0003] In the production process of dioctyl adipate and dibutyl phthalate, esterification kettles are often used. The weight of the commonly used esterification kettles is relatively fixed, and it is not easy to move and install. During the production pressurization process, the connection pipes are prone to loosening and falling off.

The invention relates to the technical field of dibutyl phthalate and discloses DOA and DBP pressurized production process and equipment. A first connecting pipe is fixedly connected to the surface ofa first esterification kettle, a second esterification kettle is fixedly connected to one side of the first connecting pipe, and a second connecting pipe is fixedly connected to the surface of a second esterification kettle. According to the DOA and DBP pressurized production process and equipment, a shell, a second threaded rod, a first gear, a motor, a second gear, a threaded block and other structures on an adjusting device are arranged, a motor is started to drive the second gear to rotate, the second gear drives a second threaded rod to rotate through a first gear, and the second threaded rod drives a supporting plate to move through a threaded block, so that the supporting plate drives universal wheels to move, when the universal wheels make contact with the ground, the equipment can be pushed to move, and when the universal wheels move into sleeves, the equipment can be placed and fixed through supporting discs, the practicability of the equipment is improved, and convenience is brought to use of workers.
Description
technical field [0001] The invention relates to the technical field of dibutyl phthalate, in particular to a DOA and DBP pressurized production process and equipment. Background technique [0002] Dibutyl phthalate is the most commonly used plasticizer for polyvinyl chloride, which can make the product have good flexibility, but its volatility and water extraction are relatively high, so the durability is poor. Dibutyl phthalate is a nitric acid Excellent plasticizer based on cellulose, strong gelling ability, used in nitrocellulose coatings, has good softening effect, stability, flex resistance, adhesion and water resistance are better than other plasticizers, Dibutyl phthalate can also be used as a plasticizer for polyvinyl acetate, alkyd resin, nitrocellulose, ethyl cellulose, neoprene, and nitrile rubber. [0003] In the production process of dioctyl adipate and dibutyl phthalate, esterification kettles are often used. The weight of the commonly used esterification kett...
