Description

Sodium 5-sulphoisophthalate is a chemical compound that is the monosodium salt of sulfonated 5-sulphoisophthalic acid. It is an important raw material in the production of polycarboxylic acids, which are used as intermediates in the production of nylon and polyester. The reaction vessel for the production of sodium 5-sulfoisophthalate is usually a stainless steel pressure reactor. Sodium carbonate and sulfur trioxide react at high temperatures to produce sodium 5-sulfoisophthalate and hydrogen sulfide. The product can be purified by fractional distillation, or it can be reacted with ammonia to form ammonium sulfite, which can then be used as a fertilizer. Sodium 5-sulfoisophthalate has been shown to have fluorescence properties and can serve as a probe for hydrogen bonding between molecules.
