The method of preparing 3 - (diphenylphosphinyl) benzenesulfonic acid and sodium salt has been used in ancient times and is described in detail below.
First, react with 3 - halogenated benzenesulfonic acid, sodium salt and diphenylphosphonation reagent. First take an appropriate amount of 3 - halogenated benzenesulfonic acid and sodium salt and place it in a clean reactor. This halogen can be either brominated or chlorinated, depending on its activity and cost. Then diphenylphosphonation reagents, such as lithium diphenylphosphonate or sodium diphenylphosphonate, are slowly dripped into the kettle and cooled at a low temperature, between -20 ° C and 0 ° C. This low temperature environment can suppress the generation of side reactions. After the reaction is completed, gradually raise the temperature to room temperature, and continue to stir to make the reaction sufficient. This process needs to be carried out in an inert gas, such as nitrogen or argon atmosphere, to prevent oxidation. After the reaction is completed, the product is purified by conventional separation methods, such as extraction, column chromatography, etc.
Second, it is obtained by metal catalytic coupling of benzenesulfonic acid, sodium salt and diphenylphosphinylation reagent. In the reaction vessel, add benzenesulfonic acid, sodium salt, diphenylphosphinylation reagent, and add a metal catalyst, such as palladium catalyst, and an appropriate amount of ligand and base. Common palladium catalysts include tetrakis (triphenylphosphine) palladium, ligands such as tri-tert-butyl phosphine, and bases such as potassium carbonate Heat the reaction system to a suitable temperature, about 80 ° C - 120 ° C, and stir the reaction number. After the reaction is completed, the product can be refined by extraction, recrystallization and other means to obtain high-purity 3- (diphenylphosphino) benzenesulfonic acid and sodium salt.
Preparation of this compound requires a suitable method according to the actual situation, and strict control of the reaction conditions to obtain satisfactory yield and purity.

3 - (diphenylphosphonyl) benzenesulfonic acid is used for storage, and the animal pays attention to the general situation. This compound is specialized, so it is hidden in storage, and it is the first to cause dryness in the environment. The tide is easy to cause its dampness, and its activity is reduced. It should be stored in the water, protected from direct sunlight, and not exposed to light or induced to reduce its temperature.
In addition, the use of the water, according to the standard. Because of its irritation, it can be caused by skin damage and eye contact. Operation, equipped with anti-dampening equipment, such as gloves, eyes, etc. And this product is often involved in chemical reactions, and the dosage is very important. Amount or insufficient, can make the anti-dampening fruit partial.
And because of its storage, it is protected from mixing with other chemicals during storage. The reaction of certain substances may produce unavoidable results, so it is not stored, and it is clear, so it is easy to identify. In this way, it is necessary to ensure the safety of 3- (diphenylphosphino) benzenesulfonic acid in storage and use, so that it is effective in chemical synthesis and other applications.

3 - (diphenylphosphinyl) benzenesulfonic acid, this product is determined by the market, because its price is often affected by general factors. First, the cost of production is of paramount importance. The quality of raw materials, the production and production of raw materials are all important. If the raw materials are rare and available, the production process needs to be exquisite, and the price will be high; on the contrary, if the raw materials are often low, the production is easy, or low.
Second, the supply and demand of the market also has a big impact. If the demand in the industry is strong, but the supply is limited, the price will rise; if the demand is sluggish, the supply will be left, and the price may decline.
Furthermore, the brand quality of the company is also about the price.
In addition, external factors such as policy laws and rate fluctuations can also affect the price. Policy incentives or restrictions on production, as well as changes in raw material costs due to rate increases and decreases, can make its market float.
Therefore, in order to know its market value, it is possible to obtain information from various parties, and the ratio is different.
