Additionally, SnCl 2 is used to selectively reduce aromatic nitro groups to anilines. [11] Aromatic nitro group reduction using SnCl 2. SnCl 2 also reduces quinones to hydroquinones. Stannous chloride is also added as a food additive with E number E512 to some canned and bottled foods, where it serves as a color-retention agent and antioxidant.
Tributyltin chloride is an organotin compound with the formula (C 4 H 9) 3 SnCl. It is a colorless liquid that is soluble in organic solvents. It is a colorless liquid that is soluble in organic solvents.
Trimethyltin chloride can be prepared by the redistribution reaction of tetramethyltin with tin tetrachloride. [3]SnCl 4 + 3 Sn(CH 3) 4 → 4 (CH 3) 3 SnCl. This redistribution reaction is typically performed with no solvent because high temperatures are required and purification is simplified.
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
Stephen aldehyde synthesis, a named reaction in chemistry, was invented by Henry Stephen (OBE/MBE).This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl 2), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH 2] + Cl −) with water (H 2 O).
A Soxhlet extractor is a piece of laboratory apparatus [1] invented in 1879 by Franz von Soxhlet. [2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for ...

The structure is reminiscent of the Mo 6 S 8 subunit of the Chevrel phases.. [2] The structure of pure Sn(OH) 2 is not known. [3] Sn(OH) 2 has been claimed to arise from the reaction of (CH 3) 3 SnOH with SnCl 2 in an aprotic solvent: [3] 2 Me 3 SnOH + SnCl 2 → Sn(OH) 2 + 2 Me 3 SnCl. No crystallographic characterization is available on this ...
