Eksempler på bruk av ACETYLENE i en setning

• Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.
• The compound is prepared by the addition of arsenic trichloride to acetylene in the presence of a suitable catalyst:.
• Propulsion was then changed to a 20 hp (15 kW) acetylene engine driving two counter-rotating tractor propellers mounted on outriggers.
• Nieuwland's research was focused on acetylene chemistry and during the course of his work he produced divinyl acetylene, a jelly that firms into an elastic compound similar to rubber when passed over sulfur dichloride.
• The butanediol is derived from condensation of acetylene with formaldehyde followed by hydrogenation.
• Applications of calcium carbide include manufacture of acetylene gas, generation of acetylene in carbide lamps, manufacture of chemicals for fertilizer, and steelmaking.
• The North Petherton Rosco Acetylene Company (dating from at least 1898) may have supplied gas to the adjacent church prior to the Gas and Carbide Company.
• In the late nineteenth and early twentieth centuries, there were many irons in use that were heated by fuels such as kerosene, ethanol, whale oil, natural gas, carbide gas (acetylene, as with carbide lamps), or even gasoline.
• Fritz Klatte, a German chemist working for Griesheim-Elektron, discovers polyvinyl acetate and applies for a patent for preparing the monomer, vinyl acetate, by addition of acetic acid to acetylene using a mercuric chloride catalyst although it is not successfully commercialized at this time.
• The main application of mercuric chloride is as a catalyst for the conversion of acetylene to vinyl chloride, the precursor to polyvinyl chloride:.
• As the gunner began to point the barrel toward the water, as per standard procedure, the round cooked-off, (thermally induced firing) and struck Missouri on the signal bridge, killing Coxswain Robert Fountain and starting a fire involving an acetylene tank lashed to the railings.
• For example, in organic chemistry, carbon–carbon bond lengths are about 154 pm in ethane, 134 pm in ethylene and 120 pm in acetylene.
• On the advice of a paper of Le Chatelier that the combustion of a mixture of oxygen and acetylene in equal parts rendered a flame of more than 3000 celsius, in 1899 Charles Picard (1872-1957) started to investigate this phenomenon but failed because of soot deposits.
• Shirakawa's research on conductive polymers can be broken down into four main categories: polyacetylene thin film synthesis, the causation of metallic conductivity due to chemical doping, the creation of conjugated (double or triple bonds in a molecule which are separated by a single bond) liquid crystalline polymers, and acetylene polymerization development that used liquid crystals as solvents.
• Compounds called polyacetylenes also occur in nature, although in this context the term refers to polyynes, compounds containing multiple acetylene groups ("poly" meaning many), rather than to chains of olefin groups ("poly" meaning polymerization of).
• The Sakawa threatened to pull the tug under with her own tow wire, but quick-acting sailors were able to sever the wire with an acetylene torch before damage resulted.
• Fake landmines were laid around the town in view of the Boers and their spies within the town, and his soldiers were ordered to simulate avoiding barbed wire (non-existent) when moving between trenches; guns and a searchlight (improvised from an acetylene lamp and biscuit tin) were moved around the town to increase their apparent number.
• Note: Acetylene cylinders contain an inert packing material, which may be agamassan, and are filled with a solvent such as acetone or dimethylformamide.
• Between the ages of eleven and eighteen, he tinkered with his own electrical recording machines, launched himself off haystacks with his own home-made glider, and almost killed himself by using water-filled tar barrels and acetylene to see how high they could be waterjet propelled.
• Fritz Klatte (28 March 1880, Diepholz – 11 February 1934) was a German chemist and the discoverer of polyvinyl acetate, with German patent (GP 281687 1912) for its preparation from acetylene gas.
