Potassium sulfide (2:1) Standards and Recommendations

DOT Classification:  4.2; Label: Spontaneously Combustible (UN 1382); DOT Class: 8; Label: Corrosive (UN 1847)

Potassium sulfide (2:1) Specification

The Potassium sulfide (2:1) with CAS registry number of 1312-73-8 belongs to the class of Inorganics. The IUPAC name is dipotassium sulfide. Its EINECS registry number is 215-197-0. In addition, the formula is K2S and the molecular weight is 110.2616.

The preparation and uses of Potassium sulfide (2:1): the anhydrous potassium sulphide can be prepared by potassium and sulfur in liquid ammonia. You should steam out of the remaining NH3. The reaction needs long time for vacuuming and half an hour for tempering at 400-500 °C. It can be used as the analysis, hair removal and pesticides.

When you are using this chemical, please be cautious about it as the following: it is very toxic to aquatic organisms and can cause burns. when it contact with acids, it liberates toxic gas. You should avoid release to the environment. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.). At last, you should refer to special instructions/safety data sheets.

You can still convert the following datas into molecular structure:
(1)SMILES: [K+].[K+].[S-2]
(2)InChI: InChI=1/2K.S/q2*+1;-2
(3)InChIKey: DPLVEEXVKBWGHE-UHFFFAOYAJ
