n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Linde Gas gaseus nitrogen plant. Linde PLC is a global multinational chemical company. It was created as a result of a merger in 2018 of American company Praxair and Linde AG and is domiciled in Ireland and headquartered in the United Kingdom. Linde is the world's largest industrial gas company by market share and
Acetylene is a moderately common chemical in the universe, often associated with the atmospheres of gas giants. [50] One curious discovery of acetylene is on Enceladus, a moon of Saturn. Natural acetylene is believed to form from catalytic decomposition of long-chain hydrocarbons at temperatures of 1,700 K (1,430 °C; 2,600 °F) and above ...
A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
In 1895 refrigeration compression cycles were further developed to enable the liquefaction of air, [25] most notably by Carl von Linde [26] allowing larger quantities of oxygen production and in 1896 the discovery that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive allowed the safe bottling of acetylene. [27]
Linde Hydraulics was established as a division of Linde Material Handling, a Linde AG business unit. Production of the first forklift truck with hydrostatic transmission began. 1984: Linde and Linde Hydraulics introduced the load sensing valve technology. 1994: Introduction of the 02 Series axial piston pumps and motors with a swash angle of 21 ...
Acetylene can readily explode when in liquid or solid form or while being pressurized, if it is pure. Dalén himself was blinded in an acetylene explosion. In 1896, French chemists Georges Claude and Albert Hess discovered that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive. [ 1 ]
As a fuel, acetylene's primary disadvantage in comparison to other fuels is its high price. As acetylene is unstable at a pressure roughly equivalent to 33 ft (10 m) underwater, water-submerged cutting and welding is reserved for hydrogen rather than acetylene. Compressed gas cylinders containing oxygen and MAPP gas
