Shanghai Tripod explains the application fields and production methods of triphenylphosphine


Triphenylphosphine is a basic raw material for ruthenium-phosphine complex catalysts and has a wide range of applications in domestic petrochemical industries. Triphenylphosphine is also used in the pharmaceutical industry, organic synthesis, and analysis. Triphenylphosphine can also be used as a brightening agent for dyestuffs, high-molecular polymer, antioxidant for color film imaging, stabilizer for polyepoxidation, and also as an analytical reagent.

Triphenylphosphine Application:

Triphenylphosphine is a triphenyl substituent of phosphine. It mainly exhibits reducing and nucleophilic properties. The application fields are as follows:

1. An important ligand for homogeneous catalysts used in the production of petrochemicals and fine chemicals.

2, Ruthenium phosphine complex catalyst base materials.

3, vitamin D2, vitamin A, clindamycin and other drugs and plant pigments play an important role in the reaction.

4, Lightening agent in the dye industry, heat stabilizers, light stabilizers, antioxidants, flame retardants, antistatic agents, rubber antiozonants, analysis reagents.

Triphenylphosphine production method:

The preparation method is that phenol is used as a raw material, and after the esterification reaction and then vacuum distillation, the triphenyl phosphite is obtained.


The specific process is divided into batch method and continuous method.

(1) Batch method

Phenol is added to the reactor, warmed and added after melting. The reaction starts with phenol at 70-90°C. After the addition, the temperature of the reaction mixture rises to about 150°C; the dissolved hydrogen chloride is removed under reduced pressure at high temperature and unreacted. Phenol is a product.

(2) Using a tower reactor

Phenol was admitted from below the upper condenser of the tower and from above the lower receiver of the tower. The two are reacted in a tower, the product is collected in a receiver, and byproduct hydrogen chloride is introduced into the absorber through the upper end of the condenser. Crude esters are obtained by distillation and other treatments.

Need to do some quick cleaning on your lawn equipment, stairs, patios, fencing, farm equipment car, name it- sometimes doing the cleaning manually can be quite exhausting for you. If you have been thinking that the market offers pressure washer for commercial cleaning only. Then here is the good news: there are great petrol pressure washer in the market that have been designed just for your domestic cleaning needs. The good thing is, these pressure washers are quite efficient at the cleaning job and consume fuel efficiently and they come at a fairly cheap price.

The best petrol pressure washer on the market is going to have a few baseline characteristics. For one thing, people need to be able to use their pressure washers effectively, so the best petrol pressure washer is going to be relatively light and easy to maneuver. Good pressure washers ideally aren`t going to have a strong fuel odor, although this is a very real and sometimes unavoidable problem with almost anything that is going to use gasoline. Good pressure washers are also versatile. This should be the sort of device that people can use to clean almost anything around the exterior of their homes. The good pressure washers need to emit the right levels of pressure. While people are usually going to have to compromise on some baseline characteristics, they should usually be able to find the best petrol pressure washer on the market that will manage to generally satisfy all of their needs.

If you are not yet aware of them, then below is a look of some of the best Petrol Pressure Washers that will work for you.
