19] reported the synthesis of silica xerogels from coal gangue by ambient drying of trimethylchlorosilane modified gels; the 88.
Silylation was done to derivatized all samples for GC/MS analysis by which , an active hydrogen is replaced by an alkylsilyl group such as Trimethylchlorosilane ( TMCS) or N-Methyl-N- trimethylsilyltri-fluoroacetamide+ 1% Trimethyl- chlorosilane and N,o- Bis(trimethylsilyl) trifluoroacetamide (BSTFA) .
N, O-bis(trimethyl)silyltrifluoroacetamide, BSTFA, (150[micro]l) containing 1% trimethylchlorosilane (TMC) were added to each tube and heated at 60[degrees]C for 30 minutes.
Electrodes were silanized in batches of five by selectively exposing the ion-selective barrel to saturated trimethylchlorosilane (Pierce, Rockford, IL) vapor at room temperature for 1 min and baking them in a 250 [degrees]C oven for 1 h.
Trimethylchlorosilane (TMCS) solutions were used for particle methylation (Crawford et al.
N,O,-bis(trimethylsilyl)trifluoroacetamide with 10% trimethylchlorosilane (N,O,-bis(trimethylsilyl)trifluoroacetamide; BSTFA) was obtained from Pierce Chemical (Rockford, IL).
Adicionaram-se 1ml de pyridine, para solubilizacao, 200[micro]L de hexamethyldisilasane (HMDS) e 100 [micro]L de trimethylchlorosilane (TMCS), para a metilacao, ate que ocorresse a formacao de um precipitado branco.
Bis-(trimethylsily)trifluoro-acetamide (240 [micro]l) and trimethylchlorosilane (120 [micro]l) were added to the 3 mg saponified oil.
The derivatizing agent was N,O-bis (trimethylsilyl) trifluoroace tamide (BSTFA) with 1 percent trimethylchlorosilane (1 percent TMCS) as catalyzing agent (Pierce, Rockford, Illinois).
1963), by adding 400 wL pyridine, 80 [micro]L hexamethyldisilizane, and 40 [micro]L trimethylchlorosilane.
Various derivatizing reagents, including dimethyldichlorosilane, trimethylchlorosilane, acetic anhydride, and trifluoroacetic anhydride, were evaluated for their ability to enhance the volatility of metabolites containing hydroxyl groups, and improve chromatographic separation.
32), using paraformaldehyde, trimethylchlorosilane mixture as chloromethylation agent and stannic chloride as catalyst.
