Glossary
Alkoxylation
A chemical process in which ethylene and/or propylene oxide is added to a substrate (a hydroxyl group-bearing compound or amine) in order to make it more soluble in water. The process is a polymerisation reaction that yields a substrate featuring polyoxyethylene and/or polyoxypropylene chains.
Biocides
Active substances or preparations that destroy, deter or inhibit microorganisms or their growth
Conditioning
The continuous application of chemicals in order to prevent or reduce the accumulation of deposits on machine clothing
Dispersing agent (paper industry)
Chemicals designed to prevent or slow down the build-up of organic and inorganic deposits in the paper machine cycle
Esterification
Condensation and equilibrium reactions between hydroxy group-bearing compounds and carboxylic acids in the presence of a catalyst to form esters.
FTIR
Fourier-Transform Infrared-Spectroscopy: used mainly to analyse the structure mainly of functional groups
GC-MS
Gas chromatography-mass spectrometry (GC-MS) is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample.
Greenbentin
Kolb Product range: nonionic surfactants, manufactured with at least 30 % natural raw materials.
Heat recovery
A technology which makes it possible to reuse the heat of reactions for the heating of further batches
HPLC
High-performance liquid chromatography (HPLC) is a form of column chromatography that is used frequently in biochemistry and analytical chemistry to separate, identify, and quantify compounds. HPLC utilises a column that holds chromatographic packing material (stationary phase), a pump that moves the mobile phase(s) through the column, and a detector that shows the retention times of the molecules. Retention times vary depending on the interactions between the stationary phase, the molecules being analysed, and the solvent(s) used.
The sample to be analysed is introduced in small volumes to the stream of mobile phase. The analyte's motion through the column is slowed by specific chemical or physical interactions with the stationary phase as it traverses the length of the column.
Ingreendients
Play on words with "green" and "ingredients" to highlight a certain group of environmentally safe ingredients
KLG
Continuous air content measuring device to determine air content during the paper manufacturing process
Methylation
A transfer of methyl groups in a chemical reaction from one molecule to the other.
Methylation is a special type of alkylation.
NMR
Nuclear magnetic resonance (NMR) is a spectroscopic method that enables the analysis of the electronic environment of individual atoms and their interaction with neighbouring atoms. This information often enables the structure and dynamics of molecules to be determined and is used in organic chemistry and biochemistry in particular. Many scientific techniques exploit NMR phenomena to study molecular physics, crystals and non-crystalline materials through NMR spectroscopy. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI).
