Sulpiride can be synthesized from 5-aminosulfosalicylic acid

N2 - The oxidative reactivity of THF derivatives formed during THF/nC 60 synthesis was evaluated with indigo dye as a model compound. The results showed that the formation of previously undetected oxidizing agents during THF/nC 60 synthesis accounted for the degradation of indigo dye by THF/nC 60 (THF/nC 60/unwashed), while THF/nC 60 after vigorous washing (THF/ nC 60/washed) and nC 60 prepared without the use of THFwere not reactive. γ-Butyrolactone (GBL) was detected by GC-MS in the THF/nC 60/unwashed as one of THF derivatives, but showed no reactivity with indigo dye. An organic peroxide was detected in the THF/nC 60/unwashed by HPLC,and was reactive with indigo dye. This compound was found to also account for the elevated antibacterial and bactericidal activities of THF/ nC 60/unwashed on E. coli. Analysis by LC/(+ESI)MS and 1H NMR showed that the detected THF peroxide was tetrahydro-2-(tetrahydrofuran-2- ylperoxy)furan. The formation of THF peroxide during the preparation of aqueous stable C 60 aggregates provides another potential explanation for the reactivity and oxidative stress mechanisms of THF/nC 60 system reported in the literature, although it does not exclude the potential reactivity and toxicity of nC 60 itself.

In recent times, around 2 million tons of BDO have been produced in the entire BDO market, but only 20% of it is traded in the freely accessible market, while the other four-fifths are processed internally to derivatives by the manufacturers. As an intermediate product, BDO is an important raw material for the synthesis of other substances, in particular of tetrahydrofuran (THF), polybutylene terephthalate (PBT) and gamma-butyrolactone (GBL).
