Chemische Eigenschaften
clear light yellow to yellow liquid
Verwenden
1-Thionaphthol is used to produce the di-[1]naphthyl disulfide. It is also used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.
Allgemeine Beschreibung
1-Naphthalenethiol (1-NAT) is a standard analyte that can be diffused in the polymeric network for the detection of optical properties.
l?uterung methode
It is steam volatile and is purified by distillation in the absence of O2, as it oxidises to the disulfide. It is soluble in Et2O and EtOH but very slightly soluble in H2O and dilute alkalis. The S-ethyl derivative, [17539-31-0] M 188.2, has b 175-176o/25mm, and do 1.120. [Beilstein 6 III 2943, 6 IV 4241.]
