Sodium phenolate has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following are some upstream and downstream products related to sodium phenol salt:

1. Upstream products:

(1) Phenol: Phenol is one of the main raw materials of sodium phenol salt. Sodium phenol salt is prepared by the reaction of phenol and sodium hydroxide. As an important basic chemical raw material, phenol is widely used in synthetic resins, pharmaceuticals, pesticides, dyes and other fields.

(2) Sodium hydroxide: Sodium hydroxide is another raw material used in the production of sodium phenolate, by reaction with phenol, to produce sodium phenolate and water. Sodium hydroxide is widely used in chemical production, and can be used as a strong base to neutralize acidic substances and adjust pH value.

2. Downstream products:

(1) Phenolic resin: Phenolic sodium salt can be used as one of the raw materials to react with formaldehyde to produce phenolic resin. Phenolic resin has excellent heat resistance, corrosion resistance, electrical insulation and other properties, widely used in plastics, rubber, coatings, adhesives and other fields.

(2) Epoxy Resin: Sodium phenol salt can also be used to produce epoxy resin. Epoxy resin has excellent mechanical properties, electrical insulation, chemical resistance, etc., widely used in electronics, electrical, coatings, composite materials and other fields.

(3) Phthalic anhydride: Phenol sodium salt can be used as one of the raw materials to react with phthalic anhydride to produce phthalic anhydride. Phthalic anhydride is an important organic chemical raw material used in the production of plasticizers, unsaturated polyester resins, pesticides and so on.

(4) Salicylic acid: Phenol sodium salt can be used to produce salicylic acid. Salicylic acid is a commonly used pharmaceutical raw material, with antipyretic, analgesic, anti-inflammatory and other effects, widely used in medicine and daily chemical fields.

In short, the upstream and downstream related products of sodium phenol salt are extensive, involving many fields, such as plastics, rubber, coatings, medicine, pesticides, etc.
