Studies were carried out to determine the kinetics of the curing reaction of the glycidyl carbamate functional oligomers with multifunctional and model amines
Model reactions between dimethyl terephthalate (DMT) and respectively a primary, a secondary, a tertiary aliphatic amine
, and a primary aromatic amine
were performed at 250[degrees]C in order to investigate the possible interaction of these different amines
with the predominant functional groups present in PET.
Figure 12 shows a plot of opacity versus particle size for the MVPs produced with the different amines
, with degrees of neutralization above 1.
Solubility in hydrocarbon liquid (in liquid-treating units): Such losses resemble vapourisation in which amines
establish equilibrium with the liquid hydrocarbon.
are not actually consumed in the core production process but rather are captured in the facility's scrubber system.
Latest Developments in the Analysis of Heterocyclic Amines
in Cooked Foods.
The Qatar Shell Research & Technology Centre at Qatar Science & Technology Park has set up an amine
solvent management programme, a technical service aimed at benefiting clients in Qatar and the region.
Chuck Martin, Strategic Marketing Manager for Gas Processing & Gas Transmission, will present a technical paper on Methyldiethanolamine (MDEA) Oxidation in Flue Gas CO2 Capture, which is a case study demonstrating Dow Oil & Gas' track record of success in meeting lower CO2 specification needs utilizing specialty amines
The best substrates for all preparations are 1,4-diaminobutane (putrescine) and 1,5-diaminopentane (cadaverine), which in nature are produced along with histamine and other biogenic amines
in protein hydrolysis during putrefaction of tissues both in living and dead organisms.
will show solid gains driven by gas sweetening applications, where their strong performance characteristics are making them more cost-effective as compared to the commodity amines
ZF-23 blend of tertiary amines
for non-CFC Maxfoam processes.
Copper can form very stable complexes with amines

are documented mutagens and carcinogens in animal models (Nagao and Sugimura 2000; Weisburger 2002), and for which there is human evidence not only of several types of high-incidence cancers, such as colon, breast, and prostate, but which also affect the heart muscle (Butler et al.
are formed during normal metabolic processes in living organisms and are present in everyday food products.
Since 18-crown-6 ether selectively complexes with primary amines
, a mixture of vancomycin and 18-crown-6 was used in CE to test the stereoselective role of the primary amine
