21260-46-8 Usage
Description
BISMUTH DIMETHYLDITHIOCARBAMATE is a lemon-yellow powder that is soluble in chloroform, slightly soluble in benzene and carbon disulfide, and insoluble in water. It is primarily used as an accelerator for natural rubber and styrene-butadiene rubber (SBR), particularly in cable covers and mechanical items.
Uses
Used in Rubber Industry:
BISMUTH DIMETHYLDITHIOCARBAMATE is used as an accelerator for natural rubber and SBR, enhancing the curing process and improving the rubber's properties, especially in cable covers and mechanical items. Its chemical properties allow it to effectively accelerate the vulcanization process, resulting in improved rubber products with enhanced durability and performance.
Check Digit Verification of cas no
The CAS Registry Mumber 21260-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,6 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21260-46:
(7*2)+(6*1)+(5*2)+(4*6)+(3*0)+(2*4)+(1*6)=68
68 % 10 = 8
So 21260-46-8 is a valid CAS Registry Number.

Coordination compounds of tin and bismuth. Complexes of tin(IV) and bismuth(III) with N,N-dialkyldithiocarbamates

Tin and bismuth metals react with N,N′,N′-tetraethylthiuramdisulfide, [Et2NC(S)S]2, and N,N,N′,N′-tetramethylthiuramdisulfide, [Mt2NC(S)S]2, in refluxing toluene to give the compounds Sn(S2CNR2)4 (R = Et, Me) in high yield. Under similar conditions bismuth gives Bi(S2CNR2)3. The reaction of metallic tin with a mixture of iodine and [R2NC(S)S]2 gives the compounds SnI(S2CNR2)3, and SnI2(S2CNR2)2. Similarly, with mixtures of [R2NC(S)S]2 and I2, bismuth yields BiI(S2CNR2)2 and BiI2(S2CNR2). Adducts of Bi(S2CNR2)3 with 1,10-phenanthroline and 2,2′-bipyridyl were also prepared. The compounds and adducts were characterized by microanalyses, infrared, UV/Visible spectroscopy and conductivity measurements.
