Problems solved by technology

Its existing problems: the product inevitably contains phenol, and phenol is a substance harmful to the human body and the natural environment, which does not meet the current market requirements for environmental protection and human contact products;
[0004] 2. Prepared by reacting phosphorus trichloride and octanol, a large amount of acid-binding agent needs to be added, and the by-product is a large amount of acid-binding agent hydrochloride. The existing problem: a large amount of solid waste is generated;
[0005] 3. The preparation device of tri-isooctyl phosphite in the prior art needs the driving component to drive the heat sink to dissipate heat and the driving component to drive the stirring component to achieve stirring when it is in use, resulting in relatively energy consumption and unable to fully utilize its energy ;

Embodiment 1

[0037] Such as Figure 1-Figure 6 As shown, the preparation device of a green and environment-friendly tri-isooctyl phosphite provided in this embodiment includes a base 5 and a preparation shell 1 installed on the top of the base 5, and the preparation shell 1 is prepared along the inner side of the base 5. 1 A rotary rod 12 is installed in the axial direction, and an outer tube 13 is installed on the outer side of the rotary rod 12 through bearings, and the outer tube 13 is installed with connecting rods 18 equidistantly along its axial direction, and the connecting rods 18 are close to the outer tube 13 places are equipped with a fixed plate 19, and the inner middle part of the fixed plate 19 is installed on the outside of the outer tube 13, the end of the connecting rod 18 away from the rotating rod 12 is hinged with a hinge block 20, and the cover body stirring blade 17 is welded on the hinge block 20, The outer side of the connecting rod 18 away from the end of the outer...

Embodiment 2

[0048] Such as Figure 1-6 Shown, a kind of preparation method of green environment-friendly type triisooctyl phosphite comprises the steps:

[0049] Step 1: Add trialkyl phosphite, octanol and catalyst to the inside of the preparation shell 1 through the liquid inlet pipe 33;

[0050] Step 2: start the electric heater 32 to heat the electric heating plate 14, and heat the liquid inside the preparation shell 1 through the heat pipe 15;

[0051] Step 3: heating and reacting the liquid in the preparation shell 1 to generate steam that hits the cover stirring blade 17 to drive the outer tube 13 to rotate to stir the liquid in the preparation shell 1;

[0052] Step 4: Collect the generated steam through the horizontal air inlet pipe 25 to the inside of the separation cylinder 23;

[0053] Step 5: The rotation of the outer tube 13 drives the rotating rod 12 to rotate, the rotating rod 12 drives the first transmission pulley 11 to rotate, the first transmission pulley 11 drives th...

Abstract

The invention discloses a preparation device and a preparation method of green and environment-friendly triisooctyl phosphite and belongs to the technical field of triisooctyl phosphite preparation devices. The trialkyl phosphite, octanol and a catalyst are stirred without a driving assembly; an energy-saving function is achieved; a fan does not need to be driven by a driving assembly to cool andliquefy triisooctyl phosphite; the energy-saving function is further achieved; trialkyl phosphite, octanol and the catalyst are added to generate triisooctyl phosphite, harmful substances will not begenerated even if the product is under a hydrolysis condition, and the requirement of the market for environment-friendly phosphite is met; hydrochloric acid is not generated, and an acid-binding agent is not needed in the preparation process, so that a large amount of acid-binding agent hydrochloride solid wastes are not generated.

Description

technical field [0001] The present invention relates to a preparation device for tri-isooctyl phosphite, in particular to a green and environment-friendly preparation device for tri-iso-octyl phosphite, and also to a method for preparing tri-iso-octyl phosphite, in particular to a The invention discloses a method for preparing green and environment-friendly triisooctyl phosphite, which belongs to the technical field of triisooctyl phosphite preparation equipment. Background technique [0002] There are two main methods for the production of current tri-isooctyl phosphite: [0003] 1. Prepared by transesterification reaction of excess octanol and triphenyl phosphite, the main product is triisooctyl phosphite, and the by-products are phenol and excess octanol. Its existing problems: the product inevitably contains phenol, and phenol is a substance harmful to the human body and the natural environment, which does not meet the current market requirements for environmental prote...
