Hydroxynitrile lyase at the diisopropyl ether/water interface: evidence for interfacial enzyme activity.

A Hickel et al.

Biotechnology and bioengineering, 65(4), 425-436 (1999-10-03)

A novel recycle reactor has been designed to determine the interfacial activity of hydroxynitrile lyase in a diisopropyl ether (DIPE)/water two-phase system. The reactor provides a known interfacial area. Enzyme activity toward mandelonitrile cleavage is continuously measured in the reactor

Unimolecular metastable decompositions of 1,1,1-trifluoroisopropyl methyl ether [CF3(CH3)CHOCH3] upon electron ionization.

Susumu Tajima et al.

Rapid communications in mass spectrometry : RCM, 17(5), 503-506 (2003-02-19)

Molecular interaction study of the diisopropyl ether-propionic acid mixture by spectroscopic and dielectric studies.

G Arivazhagan et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 81(1), 172-177 (2011-07-08)

FTIR and 13C NMR spectral studies have been carried out on diisopropyl ether-propionic acid binary mixture to probe the molecular interactions and stoichiometry of complexation. Density functional theory (DFT) calculations of vibrational frequencies of pure acid and ether-acid binary mixtures

Quantitative determination of CGP 53,437, a new HIV protease inhibitor, in plasma by high-performance liquid chromatography and fluorescence detection.

G Flesch et al.

Journal of chromatography. B, Biomedical applications, 657(1), 155-161 (1994-07-01)

A specific and sensitive liquid chromatographic assay for CGP 53,437 (I), a potent HIV protease inhibitor, is described. The method is based on a deproteinization step, followed by a liquid-liquid extraction with diisopropyl ether. Then a deprotection step of the

Cross-linked enzyme aggregates (CLEAs): stable and recyclable biocatalysts.

Sheldon RA.

Biochemical Society Transactions, 35(6) (2007)

Air-water transfer of MTBE, its degradation products, and alternative fuel oxygenates: the role of temperature.

Hans Peter H Arp et al.

Environmental science & technology, 38(20), 5405-5412 (2004-11-17)

The gasoline oxygenate methyl tert-butyl ether (MTBE) has become one of the world's mostwidespread groundwater and surface water contaminants. As a result, there has been increasing interest in the environmental behavior of MTBE and its degradation products, mainly tert-butyl formate

Enhancing crystalline properties of a cardiovascular active pharmaceutical ingredient using a process analytical technology based crystallization feedback control strategy.

Ali N Saleemi et al.

International journal of pharmaceutics, 430(1-2), 56-64 (2012-03-28)

Pharmaceutical regulatory bodies require minimal presence of solvent in an active pharmaceutical ingredient (API) after crystallization. From a processing point of view bigger crystals with minimal agglomeration and uniform size distribution are preferred to avoid solvent inclusion and for improved
