301-10-0 Usage
Chemical Properties
White or light yellowish brown paste. Soluble in petroleum ether, insoluble in water. low toxicity of Stannous octoate, oral acute poisoning data of rats LD50=3400mg/kg. acute percutaneous poisoning data of rabbits LD50>2000mg/kg.
Uses
Different sources of media describe the Uses of 301-10-0 differently. You can refer to the following data:
1. Stannous octoate is susceptible to hydrolysis and oxidation and cannot be used in combination polyethers (premixes). Its catalytic activity is higher than that of dibutyltin dilaurate.Stannous octoate can be used as a catalyst for polyurethane, mainly in the production of soft block polyether type polyurethane foam, but also as a catalyst for polyurethane coatings, elastomers, room temperature curing silicone rubber, etc. As it is a divalent tin compound, it may be oxidized to tetravalent tin compound itself after foaming, and it remains in the foam body to play the role of an antioxidant, which stays in the foam after foaming and has no adverse effect on the foam performance.
2. Tin(II) 2-ethylhexanoate is used as a polymerization initiator in polylactic acid production. It acts as an intermediate as well as a catalyst for urethane foams, lubricants, addition agents and stabilizers for transformer oils.
3. A catalyst for polylactide polymerization.
Preparation
Stannous octoate is produced by reacting 2-ethylhexanoic acid with sodium hydroxide to form sodium 2-ethylhexanoate, which then undergoes a complex decomposition reaction with stannous chloride by heating in an inert solvent.
Hazard
Toxic material.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 301-10-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 301-10:
(5*3)+(4*0)+(3*1)+(2*1)+(1*0)=20
20 % 10 = 0
So 301-10-0 is a valid CAS Registry Number.
