Zinc bis(N,N-diethylcarbamodithioate)

Zinc bis(N,N-diethylcarbamodithioate) is an organometallic compound with the molecular formula C10H20N2S4Zn and CAS number 14324-55-1. This zinc-based dithiocarbamate has a molecular weight of 361.9 g/mol and belongs to the family of metal carbamates. It is primarily used as an accelerator in rubber vulcanization processes and exhibits moderate toxicity with skin and eye irritation properties.

Zinc bis(N,N-diethylcarbamodithioate) typically appears as a white to off-white crystalline powder with a characteristic sulfur-like odor. It has limited water solubility but dissolves well in organic solvents such as acetone and chloroform. The compound is stable under normal conditions but may decompose when exposed to strong acids or high temperatures, releasing potentially harmful sulfur compounds.

Zinc bis(N,N-diethylcarbamodithioate) is primarily used as a vulcanization accelerator in the rubber industry for manufacturing tires, seals, gaskets, and other rubber products. It facilitates the cross-linking process during rubber curing, improving the final product's mechanical properties. Additionally, it finds applications in the production of latex products and serves as an intermediate in certain chemical synthesis processes.

Safe handling of zinc bis(N,N-diethylcarbamodithioate) requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its skin and eye irritation properties. Ensure adequate ventilation to prevent inhalation exposure. Avoid direct skin contact and use in well-ventilated areas. Workers should be trained on proper handling procedures and emergency response protocols.

Zinc bis(N,N-diethylcarbamodithioate) should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed and store away from strong acids, oxidizing agents, and incompatible materials. Maintain storage temperatures below 25°C and ensure proper segregation from food, feed, and drinking water. Use appropriate containment measures to prevent environmental release.

In case of skin contact with zinc bis(N,N-diethylcarbamodithioate), immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. Seek medical attention if irritation persists or symptoms develop.

Disposal of zinc bis(N,N-diethylcarbamodithioate) must comply with local and national waste regulations due to its environmental hazard classification. The material should be treated as hazardous waste and disposed of through licensed waste management facilities. Never discharge into sewers, water courses, or onto the ground. Collect spillages and contaminated materials in appropriate containers for proper disposal through authorized chemical waste handlers.

Zinc bis(N,N-diethylcarbamodithioate) is classified as ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transport purposes. It requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Shipments must include proper shipping names, hazard labels, and safety data sheets. Transport vehicles should be equipped with appropriate emergency equipment and drivers must have proper training for hazardous materials transport.

Zinc bis(N,N-diethylcarbamodithioate) is subject to REACH regulation requiring registration for manufacturing or importing above one tonne annually. It is classified under CLP regulation with hazard pictograms GHS07 and GHS09, requiring appropriate labeling and safety data sheets. While not currently listed as SVHC, it requires compliance with chemical safety assessments and may be subject to additional national restrictions in some European countries.
