This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
The reaction of itaconic anhydride with N2:CHCO2Et or Ph2C:N2 gave the expected spiro-derivs., which spontaneously rearranged; specifically, the adduct from Ph2C:N2 loses a dinitrogen mol., yielding a spirocyclopropane related to the known 5-azaspiro[2.4]h ...
A classification methodology for the automatic detection of start- and endpoints of chemical and biotechnological reaction systems from spectral reaction data is proposed. In the calibration phase, several batch experiments must be conducted covering the e ...
This project aims at the optimization of chemical reactions by using online analytical and chemometric methods. The experiments are carried out in a fully automated chemical reactor (1 liter). The host computer controls the standard process variables such ...
A method for encapsulating a core material within a capsule having a permeable or semipermeable membrane is disclosed using a complex formation reaction between oppositely charged polymers, wherein one of the polymers is an oligosaccharide such as chitosan ...
A method to obtain quantitative information about the chemical composition spatial distribution on rough (Ra between half a micrometer and tens of micrometers) surfaces is developed by using a Raman microscopy technique. It is tested on a wrinkled polyeste ...
The reaction of aldehydes, amines and TMSCN in the presence of 2-iodoxybenzoic acid (IBX) and tetrabutylammonium bromide (TBAB) afforded alpha -iminonitriles, e.g. 4-MeOC6H4C(C==N):NCH2CH2Ph, in good to excellent yields under mild conditions. The presence ...
We present an investigation into femtosecond time-resolved vibrational sum frequency spectroscopy as a tool for studying ultrafast surface dynamics. It is demonstrated that the presence of experimentally observed new spectral features does not necessarily ...
The rapid and complete characterization of chemical reaction mechanisms is of the utmost importance in terms of chemical understanding, safety and efficiency. In this presentation a new small volume reaction calorimeter (25-45mL) is described. With this re ...
Chem. mechanisms are used in 3D air quality models as well as for modeling lab. expts. Depending on the application the required detailedness of the mechanism differs. The mechanism generation program CHEMATA (Chem. Mechanism Adaptation to Tropospheric App ...
