Thus, due to the higher electron density, alkyl amine is more basic than ammonia. Q2 Is the primary amine or secondary amine more basic? In the gaseous phase, tertiary amine > secondary amine > primary amine is the order of basicities of amines. Q3 What is the structure of N-methyl...
spectrochemical analysis/ solid-state primary aliphatic aminesammonium amidesinfrared spectroscopyoctadecylaminefluid-phaseThe infrared spectra of primary alkylamines largely belong to one of two different types as found out by a systematic data search. This search was motivated by observing before an ...

Alternatively, the bis-amines are obtained by alkylation of the thiocolchicine nitrogen with suitable halogen- or tosyl-derivatives. In rare cases the bis-amines are prepared from the corresponding bis-amides through reduction with boranes. The compounds with different G1 and G2 are prepared in ...
The 2D-ATR-FTIR-COS analysis uncovered practical amides (CN, CC, CO flexing, -NH bending in amines) of EPS had been preferentially changed, which resulted in the domination of polysaccharides relevant functional teams at higher pCO2. 1H NMR analysis of EPS verified the lack of chemical signals...
The amines contain 2-100 alkylene gps. and/or poly(oxy(2-4C)alkylene)1-40 (1-10C)alkylene gps. Multi-functional amides derived from the latter have formulae (I) or (II); A = 1-20C alkyl or H; T = H or CH3; R = 4-13C neoalkyl; n = 1-40; x, y, z = 1-8; and x...

The lower presence of bacteria not only occurred in the tests carried out on the samples with a high concentration of Legionella (7.1 x 106) in the initial sample, but also in those test dishes with an initial bacterial composition of more than 1000 times lower. Therefore, the result of th...
