Tinopal

A problem that has been encountered with many dyes is that they tend to degrade in sunlight. The SDTF studied fluorescent dyes in various laboratories and found that Eosine OJ and Tinopal CBS-X were relatively stable. However, when the same dyes were used in the field, it was discovered that they were not stable under warm and humid conditions owing to aqueous photolysis. The SDTF therefore decided to use dilute active ingredient and metal tracers that were more stable.

Tobacco primary cell wall and normal bacterial Acetobacter xylinum cellulose formation produced a 36.8 3A triple-stranded left-hand helical microfibril in freeze-dried Pt-C replicas and in negatively stained preparations for transmission electron microscopy (TEM). A. xylinum growth in the presence of 0.25 mM Tinopal disrupted cellulose microfibril formation and produced a... 

Figure 2. Freeze-dried A. xylinum cellulose grown in the presence of 0.25 mM Tinopal and replicated with 16.4A Pt-C and backed with 156A of carbon. A tangled mass of 33A Pt-C coated submicrofibrils was formed instead of normal ribbon cellulose.

Previous work has shown that the presence of Calcofluor or Tinopal could dramatically increase A. xylinum cellulose synthesis. This observation was the basis for the hypothesis that cellulose polymerization can be uncoupled from a slower sequential crystallization step (2-5). We believe the hypothesis is not consistent with our observations. At the very least, the presence of an ordered and crystal-like submicrofibril produced in the presence of 0.25 mM Tinopal would relegate Tinopal s or Calcofluor s effects to an event occurring after the initial cellulose polymerization-crystallization step or steps.

An early example of a monosubstituted stilbene was introduced by Geigy as Tinopal RBS (89) and used for cotton and polyamide (nylon). Conversion of the sulfonic acid group into A-ethylsulfonamide, via the sulfonyl chloride, yields an FBA for polyester and plastics (55USP2713057). The triazole ring is formed by diazotization of the 4-aminostilbene followed by coupling with 2-naphthylamine and oxidation with ammoniacal copper(II) sulfate, occasionally in pyridine (21CB2191).
