what is destructive distillation of coal? give uses of all the products obtained
Answers
Answer:
Destructive distillation is the chemical process of the decomposition of unprocessed material by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols. It is an application of pyrolysis. The process breaks up or 'cracks' large molecules. Coke, coal gas, gas carbon, coal tar, ammonia liquor, and "coal oil" are examples of commercial products historically produced by the destructive distillation of coal.
Answer:
destructive distillation of coal refers to the heating of coal in the absence of oxygen for higher temperatures like thousand degree Celsius we do so because to obtain several products from it call is not a a single compound but it is a mixture of many of the hydrocarbons some of these important compounds separated from coal by the destructive distillation of coal are first cook it is a tough Porus and black substance left as a Residue of destructive distillation of coal it is almost pure form of carbon it is a good fuel with the high calorific value and burns with no smoke it is an excellent reducing agent used in metal industry it also used to prepare industrially important gases like water gas and producer gas it is also helpful in the production of Acetic Acid and plastic like polyvinyl chloride apbc next is Coal Tar is a black liquid with unpleasant smell it is a mixture of many 200 compounds which can be separated by the fractional distillation compounds are obtained from Coal Tar stolen when is phenolphthalein and Crocin accept it is used to make medicines dice paint explosives plastics synthetic fibre pesticide Kota is also used in the surfacing of roads and waterproof Rose School gas it is obtained during the processing of coal to get Coke it is a mixture of hydrogen Methane carbon monoxide and other gases it is a very good fuel and with high calorific value earlier days it was useful cooking and light not these fuels are industrially important and because of the presence of hydrogen it is also used for many chemicals in Metallurgy process to create reducing atmosphere next is America liquid some and ammonium compounds are also produced during the destructive distillation of coal when dissolved in water give chemical liquid when ammonia is reacted with nitrogen with several acids then it forms nitrogen is compound. that's all hope u like it
