Trimethyl isocyanurate

Trimethyl isocyanurate [827-16-7] can be synthesized in 60% yield by the reaction of CA with dimethyl sulfate in alkaline medium (13) or with diazomethane (63) and in essentially quantitative yield by thermal rearrangement of trimethyl cyanurate [877-89-4]. Isomerization of alkyl cyanurates to the corresponding isocyanurates is frequendy observed (11,64).

At 200 °C, the reaction of methyl isothiocyanate and alkylene oxide gives trimethyl isocyanurate. This reaction involves the trimerization of methyl isothiocyanate followed by stepwise replacement of the sulfur by oxygen via spiro compounds. Phenyl isothiocyanate reacts with ethylene oxide to give a mixture of triphenyl isocyanurate and 3-phenyloxazolidine-2-one 90 °. The formation of the oxazolidone is caused by the reaction of the initially formed 2-phenylimino oxathiolene 89 with ethylene oxide in the presence of the catalysts... 

In an acetone extract from a neoprene/SBR hose compound, Lattimer et al. [92] distinguished dioctylph-thalate (m/z 390), di(r-octyl)diphenylamine (m/z 393), 1,3,5-tris(3,5-di-f-butyl-4-hydroxybenzyl)-isocyanurate m/z 783), hydrocarbon oil and a paraffin wax (numerous molecular ions in the m/z range of 200-500) by means of FD-MS. Since cross-linked rubbers are insoluble, more complex extraction procedures must be carried out (Chapter 2). The method of Dinsmore and Smith [257], or a modification thereof, is normally used. Mass spectrometry (and other analytical techniques) is then used to characterise the various rubber fractions. The mass-spectral identification of numerous antioxidants (hindered phenols and aromatic amines, e.g. phenyl-/ -naphthyl-amine, 6-dodecyl-2,2,4-trimethyl-l,2-dihydroquinoline, butylated bisphenol-A, HPPD, poly-TMDQ, di-(t-octyl)diphenylamine) in rubber extracts by means of direct probe EI-MS with programmed heating, has been reported [252]. The main problem reported consisted of the numerous ions arising from hydrocarbon oil in the recipe. In older work, mass spectrometry has been used to qualitatively identify volatile AOs in sheet samples of SBR and rubber-type vulcanisates after extraction of the polymer with acetone [51,246].

Blocked isocyanates are also nsed as cross-linking agents for powder coatings. Becanse of its high melting point, caprolactam blocked, l-(isocyanatomethyl)-5-isocyanato-l,3,3-trimethyl-cyclohexane (IPDI) is commonly used. Especially suited for this application are isocyanurate trimers. Despite catalysis with DBTDL, caprolactam-blocked isocyanates require a cure temperature of 180-200 °C. To achieve a lower cure temperature of about 140 °C, ketoxime-blocked isocyanates are used.i°°...
