2-(thiocyanomethylthio)-benzothiazole fungicide on leather : a review / L. Muthusubramanian in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 82, N° 1 (01-02/1998)

Titre : 2-(thiocyanomethylthio)-benzothiazole fungicide on leather : a review Type de document : texte imprimé Auteurs : L. Muthusubramanian, Auteur ; R. B. Mitra, Auteur ; V. S. Sundara Rao, Auteur Année de publication : 1998 Article en page(s) : p. 22-23 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Ten years ago the predominant fungicides used in the leather industry were phenolic based. The availability of these products changes as new active ingredients become available and as other products are considered usuitable on environmental and health and safety grounds (often prohibited by legislation in specific countries). As a result of legislation limiting the content of pentachlorophenol (PCP) in leather, fungicides based on substituted benzothiazole activities such as 2-(thiocyanomethyltio)-benzothiazole (TCMTB) were introduced and became more widely used.

Muralidharan, Auteur ; V. S. Sundara Rao, Auteur Année de publication : 1996 Article en page(s) : p. 101-105 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This study shows that first and second derivative UV spectrophotometry are useful for the analysis of OPP and PCMC respectively when present together. Linear calibration graphs were established over a concentration trange of 10-50 µg/ml.
The results were found to be comparable to GC-MSD data. The application of this simple and rapid technique for the analysis of OPP and PCMC in leather preservative formulations is described.En ligne : https://drive.google.com/file/d/1mnPdq7JPG38UkJZ1BMJ-PD6anMhf-ZYS/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8114

Tannage Résumé : Studies on the mixed or co-condensation of sulphonated and unsulphonated novolacs indicate that during the process of mixing of both sulphonated and unsulphonated products, one-third of the novolac added is getting sulphonated and two-thirds is in dispersed form. However, on final condensation, only one-fifth remains in free form and the rest of the novolac is involved in the formation of the mixed condensation product. Note de contenu : - Analytical methods

Titre : A new approach to the synthesis and formulation of 2-(thiocyanomethylthio)-benzothiazole Type de document : texte imprimé Auteurs : L. Muthusubramanian, Auteur ; R. B. Mitra, Auteur ; V. S. Sundara Rao, Auteur ; T. Ramaswamy, Auteur Année de publication : 1997 Article en page(s) : p. 160-161 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Previously fungal attack in the leather industry has been prevented by using pentachlorophenol, but its use is no longer acceptable due to the possibility of the formation of chlorinated dibenzodioxine a poisonous compound. 2-(Thiocyanomethyltio)-benzothiazole (TCMTC), which is a currently used replacement is insoluble in water, and therefore has to be applied as an emulsion to wet blue leather.
This paper reports on the synthesis and formulation of TCMTB. The synthesis of TCMTB is characterised by infrared spectroscopy, nuclear magnetic resonance and by mass spectrometry.En ligne : https://drive.google.com/file/d/1stV8VMKelb6rKgAGnMDjy_98Nfn_AOQ7/view?usp=share [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8025
