The vehicle is available in four colour options, pearl cool white, pearl nightstar black, matt carbonium
grey metallic, and pearl splendour red.
It is used for the synthesis of reactive, direct, azoic, acidic, vat, anthraquinone, indigo, phthalocyanine, carbonium
, polymethine, and nitro dye.
Dimethylnitrosamine (DMN) is metabolised by DMN-N-demethylase I leading to the generation of carbonium
ion that methylates DNA and other macromolecules.
First, a furansubstituted methylene glycol is protonated by an acid from the reaction medium, which then releases water to form a furan-substituted hydroxyl methylene carbonium

ion in the reaction of lysozyme," Journal of Molecular Biology, vol.
One of the most used compounds for studying AC in experimental models is azoxymethane (AOM), an intermediary metabolite of dimethylhydrazine that gives rise to methyl diazonium and methyl carbonium
, chemicals which are known to damage a number of biomolecules and may induce colon cancer .
On the other hand, ionic compounds are constituted in an ion-pair configuration, where the cationic species (commonly anilinium or carbonium
) takes the function of activating the alkylated active sites, while the anionic species (tetra(pentafluorophenyl)borate) prevent the interaction between the abstracted methyl and the Zr center (1), therefore the catalytic activity is better.
At pH less than 6 fuchsone is hydrated to give the leucobase and strong acid (1 N HCl) is required to form the carbonium
ion which is reducible at the dme ([?]0.645 V).
Using low heating rate, the accessibility of initial fibers for carbonium
ions (+C[H.sub.2]OH) is low.
The 10 most common medications prescribed to the 47 participants who completed the study were: Calcarea fluoric, Rhus toxicodendron, Pulsatilla, Natrum muriaticum, Bryonia alba, Thuja occidentalis, Lycopodium clavatum, Kali carbonium
, Arnica montana, Sepia officinalis.
