Tin(IV) Chloride Main Applications

Organic synthesis

Tin(IV) Chloride is an important raw material for the synthesis of organotin compounds, participating in various types of synthesis, including olefin addition reactions, ketone and aldehyde conversions, and the preparation of complex fine chemical intermediates.

Thin film deposition

It is also an important precursor for preparing functional thin films such as SnO2, and is mainly used in semiconductor processes, optoelectronic materials, and gas-sensitive sensor thin films.

Chemical materials

This compound can be used as a cationic catalyst for monomers such as isobutylene, and for glass surface treatment to form conductive coatings and improve wear resistance.

Analytical chemistry

As an analytical reagent, Tin(IV) Chloride is used in organic analysis for ethers and saponified phenols, and has good applications in analytical chemistry.

Precautions

  1. It should be strictly sealed and stored in a cool, dry, well-ventilated place, away from direct sunlight and heat sources.

  2. It should be stored in corrosion-resistant glass or Teflon containers and should not be stored with strong oxidizing agents.

  3. When handling Cl4Sn, protective gloves, protective clothing and other protective equipment must be worn. It is recommended to carry out the work in a fume hood to avoid direct contact with eyes and skin.

  4. In the event of a fire, water-based extinguishing agents must not be used; dry sand or carbon dioxide extinguishing agents should be used instead.

  5. In case of a leak, evacuate the danger zone and carefully neutralize the leaked liquid with soda ash or lime.

FAQ

1. Why can't you use water-based extinguishing agents to put out a fire?

Because using water-based extinguishing agents will generate white smoke that obstructs visibility.


2. What is the difference between Tin(IV) Chloride and Tin(II) Chloride?

Tin(IV) Chloride (SnCl4) is a tetravalent tin compound, which is more reactive and is a strong Lewis acid; Tin(II) Chloride (SnCl2) is a divalent tin compound, mainly used in reduction reactions. The two are not interchangeable.


3. Can Cl4Sn be stored in metal containers?

It is not recommended, as its strong corrosiveness can damage most metals. Glass or corrosion-resistant containers should be used instead.
