People who swallow gasoline or other liquid alkane mixtures should not be made to vomit, as this would increase the chance of getting alkanes into the lungs. The lungs become unable to expel fluids, just as in pneumonia caused by bacteria or viruses. In the lungs, however, they cause “chemical” pneumonia by dissolving fatlike molecules from cell membranes in the tiny air sacs (alveoli). Swallowed, liquid alkanes do little harm while in the stomach. A range of petroleum-based products that can be abused as inhalants. Pressurized canisters of propane and butane gas, both of which are intended for use as fuels, are abused as inhalants.įigure 7.1. Inhaling (“sniffing”) these hydrocarbons in gasoline or aerosol propellants for their intoxicating effect is a major health problem that can lead to liver, kidney, or brain damage or to immediate death by asphyxiation by excluding oxygen. ![]() Alkanes of low molar mass-those with from 1 to approximately 10 or so carbon atoms-are gases or light liquids that act as anesthetics. These effects depend on the size of the hydrocarbon molecules and where on or in the body they are applied. Storage and transportation characteristics The warehouse is ventilated and dry at low temperature it is stored separately from oxidants, acids, and food additivesįire extinguishing agent dry powder, foam, carbon dioxide, sand.Hydrocarbons are the simplest organic compounds, but they have interesting physiological effects. About 80-84g, the yield is about 80%.įlammability hazard characteristics Open flame is combustible high thermal decomposition releases sulfur oxide gas The extract is combined with crude mercaptan, washed with water, dried with anhydrous sodium sulfate, evaporated to remove benzene, distilled under reduced pressure, and the product is obtained by collecting 165-169 ℃(5.19kPa) fraction. The separated oil layer is crude mercaptan, which is extracted with benzene after acidification of the water layer. After adding 30g of sodium hydroxide and 300ml of water, the mixture is refluxed for another 2 hours. A mixture of 125g bromododecane, 38g thiourea and 250ml 95% ethanol was heated and refluxed for 3h. The production method can be synthesized in the laboratory by the following method. used as a relative molecular mass regulator for polymer compounds Used in the rubber, plastic and pharmaceutical industries Used as a polymerization regulator for synthetic rubber, synthetic fibers, and synthetic resins also used in the production of polyvinyl chloride stabilizers, drugs, pesticides, fungicides, detergents, etc. Used in rubber, plastic and pharmaceutical industries Uses Used as polymerization regulator for synthetic rubber, synthetic fiber, synthetic resin also used in the production of polyvinyl chloride stabilizers, drugs, pesticides, fungicides, detergents, etc. Soluble in methanol, ether, acetone, benzene, ethyl acetate, insoluble in water. It should be stored separately from oxidants, acids and edible chemical raw materials.Ĭhemical properties colorless or light yellow liquid. It is harmful to the environment, and attention should be paid to the pollution of the water environment and aquifer. High concentrations of inhalation cause headache, nausea, vomiting, and even coma. The vapor or fog of this product is irritating to the nose and throat. Safety Steam or fog is irritating to the nose and throat. ![]() The crude product is washed, dried, distilled, and distilled under reduced pressure, which is n -12 mercaptan. After the reaction is completed, it is cooled and left to layer, and the oil layer is crude mercaptan. Preparation Bromododecane, thiourea and 95% ethanol are heated to reflux reaction, then sodium hydroxide solution is added and heated. Uses n-twelve mercaptan can be used as a relative molecular mass regulator for polymer compounds.
