Organotin compounds represent a significant class of chemicals with diverse and critical industrial applications. Among these, Dioctyltin Oxide (DOTO) has carved out a vital niche due to its unique chemical properties and versatility. As a leading supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality DOTO, essential for numerous manufacturing processes.

What are Organotin Compounds?

Organotin compounds are organometallic compounds where organic compounds are covalently bonded to carbon atoms of organometallic compounds. In the case of organotins, these are compounds with at least one carbon-tin bond. Their properties and applications are highly dependent on the number and type of organic groups attached to the tin atom. They are widely used as stabilizers, catalysts, biocides, and intermediates in the synthesis of other chemicals.

Dioctyltin Oxide (DOTO): Properties and Structure

Dioctyltin Oxide, with the chemical formula C16H34OSn and CAS number 870-08-6, is characterized by a tin atom bonded to an oxygen atom and two octyl groups. Typically appearing as a white powder, DOTO exhibits properties such as low volatility and solubility in organic solvents, but limited solubility in water. Its stability under normal conditions makes it a preferred choice for many industrial applications. The presence of the two octyl chains influences its lipophilicity and compatibility with various organic matrices.

Key Industrial Applications of DOTO

DOTO's industrial significance stems from its multifaceted utility:

  • PVC Heat Stabilizer: A primary application is its role as a heat stabilizer for Polyvinyl Chloride (PVC). It protects PVC from thermal degradation during processing, which is crucial for maintaining the integrity and appearance of PVC products used in construction, automotive, and medical devices.
  • Catalyst in Chemical Reactions: DOTO is an effective catalyst for esterification, transesterification, and polycondensation reactions. This catalytic activity is vital in the production of coating resins, polyurethane foams, silicone sealants, and oleochemicals.
  • Intermediate for Other Organotins: It serves as a building block for synthesizing other specialized organotin compounds with tailored properties for specific industrial needs.
  • Paint and Coating Enhancer: DOTO can be used to improve the performance of paints and coatings, contributing to durability and corrosion resistance, especially in automotive applications.
