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 polymerization 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 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.
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 used frequently in biochemistry and analytical chemistry to separate, identify, and quantify compounds. HPLC utilizes 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 time varies depending on the interactions between the stationary phase, the molecules being analyzed, and the solvent(s) used.
The sample to be analyzed is introduced in small volume 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
Word game with "green" and "ingredients" to highlight a certain group of environmentally benign ingredients
KLG
Kontinuierliches Luftgehaltsmessgerät: tool to determine air content during the paper manufacturing process
Methylation
Denotion of a substitution or attachment of a methyl group on various substrates. The methylation is a special case of the alkylation process.
NMR
Nuclear magnetic resonance (NMR) is a property that magnetic nuclei have in a magnetic field and applied electromagnetic (EM) pulse, which cause the nuclei to absorb energy from the EM pulse and radiate this energy back out. The energy radiated back out is at a specific resonance frequency which depends on the strength of the magnetic field and other factors. This allows the observation of specific quantum mechanical magnetic properties of an atomic nucleus. 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).
