Results 1–5 of 5 for katalitičko hidrogeniranje
catalytic hydrogenation → katalitičko hidrogeniranje
Catalytic hydrogenation is the infusing of unsaturated or impure hydrocarbons with hydrogen gas at controlled temperatures and pressures and in the presence of a catalyst for the purpose of obtaining saturated hydrocarbons and/or removing various impurities such as sulphur and nitrogen.
catalytic cracking → katalitčko krekiranje
Catalytic cracking is a petroleum refining process in which heavy-molecular weight hydrocarbons are broken up into light hydrocarbon molecules by the application of heat and pressure in the presence of a catalyst.
formaldehyde → formaldehid
Formaldehyde (methanal) is a colourless gas, HCHO; r.d. 0.815 (at -20 °C); m.p. -92 °C; b.p. -21 °C. It is the simplest aldehyde, made by the catalytic oxidation of methanol (500 °C; silver catalyst) by air. It forms two polymers: methanal trimer and polymethanal.
palladium → paladij
Palladium was discovered by William Hyde Wollaston (England) in 1803. Named after the asteroid Pallas which was discovered at about the same time and from the Greek name Pallas, goddess of wisdom. It is soft, malleable, ductile, silvery-white metal. Resists corrosion; dissolves in oxidizing acids. Absorbs hydrogen. Metal dust is combustible. Palladium is obtained with platinum, nickel, copper and mercury ores. Used as a substitute for silver in dental items and jewellery. The pure metal is used as the delicate mainsprings in analog wristwatches. Also used in surgical instruments and as catalyst.
