CHEMISTRY GLOSSARY
polystyrene → polistiren
Polystyrene is a vinyl polymer. Structurally, it is a long hydrocarbon chain, with a phenyl group attached to every other carbon atom. Polystyrene is produced by free radical vinyl polymerization, from the monomer styrene. Polystyrene or Styrofoam is used in the construction industry as insulating material and for production of containers.
saturated fatty acid → zasićena masna kiselina
Saturated fatty acid is a fatty acid carrying the maximum possible number of hydrogen atoms (It doesn’t have any double bounds in the alkyl chain). The most important of these are:
| Butyric (butanoic acid) | CH3(CH2)2COOH |
| Lauric (dodecanoic acid) | CH3(CH2)10COOH |
| Myristic (tetradecanoic acid) | CH3(CH2)12COOH |
| Palmitic (hexadecanoic acid) | CH3(CH2)14COOH |
| Stearic (octadecanoic acid) | CH3(CH2)16COOH |
| Arachidic (eicosanoic acid) | CH3(CH2)18COOH |
smoke → dim
Smoke is a fine suspension of solid particles in a gas. In general smoke particles range downward from about 5 μm in diameter to less than 01 μm in diameter. Smoke generally refers to a visible mixture of products given off by the incomplete combustion of an organic substance such as wood, coal, fuel oil etc. This airborne mixture general contains small particles (dusts) of carbon, hydrocarbons, ash etc. as well as vapors such as carbon monoxide, carbon dioxide, and water vapor.
supercritical carbon dioxide → superkritični ugljikov dioksid
Supercritical carbon dioxide (scCO2) is a powerful, cheap, non-toxic and environmental friendly solvent. When used at a supercritical state (over 74 bar and 31 °C), it achieves similar solvating power as its organic competitors, such as hydrocarbons and chlorinated solvents. Supercritical carbon dioxide is one of few solvents that can be unrestrictedly used for food processing.
unsaturated fatty acid → nezasićena masna kiselina
Unsaturated fatty acid is a fatty acid whose carbon chain can absorb additional hydrogen atoms. Their carbon chain has one or more double or triple valence bond per molecule. The most important of these are:
| Oleic (9-octadecenoic acid) | CH3(CH2)7CH=CH(CH2)7COOH |
| Linoleic (9,12-octadecadienoic acid) | CH3(CHCH2)3(CH2CH=CH)2(CHCH2)7COOH |
| Linolenic (9,12,15-octadecatrienoic acid) | CH3(CH2CH=CH)3(CHCH2)7COOH |
