Petrochemicals have had a dramatic impact on our food clothing shelter and leisure. Some synthetics tailored for particular uses actually perform better than products made by nature because of their unique properties. The two main classes of petrochemical raw materials are olefins (including ethylene and propylene) and aromatics (including benzene and xylene isomers) both of which are produced in very large quantities. This is the first part of two volume book about the petrochemical production and process description. In the first part important petrochemical compounds alcohols and aldehydes butylenes butadiene ethylene propylene toluene styrene acetylene benzene ethylene oxide ethylene glycol acrylonitrile acetone acetic acid acetic anhydride and ammonia are discussed. In the second volume a full process description and polymerisation processes for production of high density polyethylene in a slurry and gas phases ziegler natta catalysis polymerisation process low density polythylene in a radical polymerisation as bulk phase in high pressure polypropylene in slurry and gas phases ziegler natta and metallocene catalysis polymerisation process poly vinyl chloride in a suspension radical polymerisation styrene butadiene rubber in a emulsion copolymerisation and polystyrene will be discussed. Petrochemical production processes is an invaluable reference for chemical petroleum and process engineers chemists chemical technologist petroleum analysts and students in these disciplines. This book will be a welcome addition to the reference collection of large academic libraries at universities with programs in petroleum engineering.
