Core 1 Notes: Production of Materials

1)Fossils fuels provide both energy & raw materials such as ethene, for production of other substancesIdentify the industrial source of ethylene from the cracking of some of the fractions from the refining of crudeCatalytic cracking is the process whereby full(prenominal) molecular weight fractions ar broken down to depression molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes, until ethene, propene, (or both) are formed. Catalytic Cracking allows greater output of elevated-demand products.

Identify that ethylene, because of the high matchivity of its double bond, is readily transformed into many helpful productsEthylene, because of the high reactivity of its double bond, can form many useful products, such as plastics (polyethylene). For example, ethene can react with water to form ethanol, with a H3PO4 throttle at 300oC. ethylene can react with oxygen in the strawman of an Ag catalyst and at 250oC, to form ethylene oxide, which is further treat with dilute acid solution to form ethylene glycol.



ethylene can also react with oxygen, with a copper chloride catalyst and at 150oC, to form vinyl chloride (chloro-ethene)Identify that ethylene serves as a monomer from which polymers are madeEthylene is the monomer which is converted into the polymer polyethylene by the process of polymerization (chemical reaction where many small identical molecules join together to form one large molecule).

Identify data, plan and actualize a first-hand investigation to compare the reactivities of appropriate alkenes with the corresponding alkanes in bromine water and iodine in solutionAlkanes burn in air to form CO2 and H2O, and liberate large amounts of ignite in the process. Alkanes also react with (or decolourise) Cl, Br, and I, very slowly, in the presence of ultra-violet light. However without UV-light no rxn occurs. However, alkenes are much more reactive,
