nature:
1. Phenolic sulfonic acid is an organic compound.
2. It is a solid, colorless or light yellow particle that is soluble in water and some organic solvents.
Purpose:
1. Phenolic sulfonic acid is mainly used as a raw material for dyes and pigments, as well as dye intermediates.
2. It can be used to prepare various organic dyes, such as indigo dyes, polarizing dyes, etc.
3. Phenol sulfonic acid can also be used as a functional material in fields such as wet dyes and propeller asymmetric liquid crystals.
Manufacturing method:
The preparation method of phenolic sulfonic acid can be obtained by substitution reaction of naphthalene sulfonic acid. Specifically, 2-naphthol is first reacted with concentrated sulfuric acid to produce 2-naphthol sulfonic acid, which is then oxidized by air to convert 2-naphthol sulfonic acid into phenol sulfonic acid under oxidative conditions.
Security information:
1. It is an organic acid with a certain degree of irritability.
2. During operation, attention should be paid to avoiding contact with the skin, eyes, and mucous membranes.
3. Appropriate safety measures should be taken during handling and storage, such as wearing protective gloves and goggles.
4. If discomfort occurs after ingestion or contact, seek medical attention immediately.
