Determination of dithiocarbamyl compounds in natural latex concentrate

Chooi S. Y., . Determination of dithiocarbamyl compounds in natural latex concentrate. pp. 255-265. ISSN 0127-7065

The carbon disulphide evolution procedure of determining dithiocarbamyl compounds was modified to a simple and practical method of assessing thiram (TMTD) and other dithiocarbamyl preservatives in natural latex concentrate. TMTD and its breakdown product ZDMC (zinc dimethyldithiocarbamate) were detected by thin layer chromatography in the TMTD/ZnO (TZ) dispersion but only TMTD was apparently observed in LA/TZ latex concentrate. It was proposed that for practical purposes of process control in the production of LA/TZ latex the TMTD existing either alone or with its breakdown product ZDMC could be assessed as an overall amount of TMTD.

Abstract

The carbon disulphide evolution procedure of determining dithiocarbamyl compounds was modified to a simple and practical method of assessing thiram (TMTD) and other dithiocarbamyl preservatives in natural latex concentrate. TMTD and its breakdown product ZDMC (zinc dimethyldithiocarbamate) were detected by thin layer chromatography in the TMTD/ZnO (TZ) dispersion but only TMTD was apparently observed in LA/TZ latex concentrate. It was proposed that for practical purposes of process control in the production of LA/TZ latex the TMTD existing either alone or with its breakdown product ZDMC could be assessed as an overall amount of TMTD.
