Zinc dibenzyldithiocarbamate

A survey of the extractables present in rubber teats was published in 1991. The samples were extracted with diethyl ether or acetone and the extracts analysed by GC and GC-MS. Data was obtained on 49 rubber teats commercially available in Holland and a number of compounds not permitted in the Dutch regulations were identified, including dibenzylamine, acetophenone, zinc dibenzyldithiocarbamate, 4,4 -thio-bis(2-tert-butyl 5-methyl)phenol and bis(2-hydroxy-3-tert-butyl 5-ethylphenyl)methane. 

Bismuth has been determined with the use of zinc dibenzyldithiocarbamate (CCI4, e = 1.2-10, at 370 nm) [17,18], lead tetramethylenedithiocarbamate [19], and pyrrolidine-dithiocarbamate [20]. 

Zinc dibenzyldithiocarbamate (formula 19.1), which is soluble in CCI4 and CHCI3, is less selective than Pb(DDTC)2 but more resistant to highly acidic media [20]. With this reagent, copper can be extracted from 1-2 M HCl or H2SO4. Lead dibenzyldithiocarbamate has been used similarly [21]. 

The diethyldithiocarbamate copper complex is unstable in acid medium and is light-sensitive. Dibenzyldithiocarbamate (avaUable as zinc salt) lacks these disadvantages moreover, it is more sensitive (Table 1) and more specific (M13, S3). Maytum et al. (M17) and most recently Giorgio et al. (G5) have described methods for urinary copper determination with this reagent. The latter method does not require preliminary ashing. The only disadvantage of these methods is the use of carbon tetrachloride, which is potentially toxic.
