They've been marketing tertiary amines
, fatty acids and alcohols, and other oleochemicals for years and we felt partnering with Temix would allow us to sell our tertiary amines
more effectively on a global basis.
24) Shade change or margin staining are expected consequences resulting from the oxidation of the aromatic tertiary amine
, required for initiating polymerization in chemically or dual-cured resin cements, or from inadequate polymerization.
5 wt%) as photoinitiator in the presence of a tertiary amine
and also containing 20% NS was carried out using a light cure, model VCL OPTILUX 501.
Bulab 600, 685, and 693 tertiary amine
catalysts based on TMEDA (tetramethylethylene diamine).
Alcoholysis of anhydrides is catalyzed by tertiary amines
Mechanisms for the anionic polymerization of epoxy monomers initiated by tertiary amines
have been extensively discussed [4-13].
But, recent studies with the addition N-substituted maleimides, along with tertiary amines
, BP, the efficiency of initiation is as good as photocleavage without the byproduct formation.
The tertiary amines
and their secondary amine metabolites can be measured from the same extract by using the individual assays.
These primary, secondary and tertiary amines
are distinguished by whether one, two or all three of the hydrogens in ammonia have been replaced by a carbon-based molecular fragment.
Notably, this procedure is preferred owing to the facile oxidation of tertiary amines
that form highly reactive iminium ion intermediates for further functionalization including the development of carbon-carbon or carbon-heteroatom bonds .
Total quantity or scope: The University of East Anglia is looking to purchase a versatile field-deployable GC-Time-of-Flight mass spectrometer (GC-ToF-MS) system for ultra-trace environmental air, water and soil analysis of volatile compounds (boiling point range -140 AC to 300 AC) such as halocarbons (including iodocarbons, bromocarbons, chlorocarbons, CFCs), sulphur gases (including dimethyl sulphide and carbonyl sulphide), oxygenated and nitrogenated hydrocarbons (including short-chain alcohols, aldehydes, and ketones, alkyl nitrates, and acetonitrile), persistent organic pollutants, primary, secondary and tertiary amines
