Sulzer has done pioneering work in the field of packings for distillation. The main route for producing styrene by dehydrogenation of ethylbenzene consumes a substantial amount of energy because of the use of high-temperature steam.

It is also used as a solvent, as a constituent of asphalt and naphtha, and in fuels. 0000005065 00000 n Here the offgas (mainly hydrogen, some carbon dioxide from side-reactions) is separated and measured by the flow indicator FI2 (wet gas meter). The Empirical Formula of a Compound Lab #5 Introduction A look at the mass relationships in chemistry reveals little order or sense. The need for synthetic styrene butadiene rubber (Styrene Butadiene Rubber (E-SBR)) during World War II provided the impetus for large-scale production. The reboiler is the electric heater H4 (manually adjusted). The product (mainly styrene) is cooled by the cooler C4 and pumped out of the vacuum by the geared pump P5 which is controlled by an optical sensor in the level control LC3. Both methods are used in practice. Most of it is produced by the catalytic dehydrogenation of ethylbenzene. Under ordinary conditions, ethylbenzene is a clear, colorless liquid with a characteristic aromatic odor. 0000001448 00000 n Styrene is an important monomer in the manufacture of thermoplastic.

Adiabatic reaction drops the temperature, so the outlet stream is reheated prior to passage through the second reactor. The first law places no restriction, Safety Data Sheet Aspira Scientific 521 Cottonwood Dr. Milpitas, CA 95035 408.571.1100 techsupport@aspirasci.com www.aspirasci.com Section 1: Product Identification Product Identifiers Product Name: L-, SORTING PLASTICS FOR RECYCLING INTRODUCTION Description Students use the difference in densities of polymers and flame tests as a basis for the development of a scheme to separate plastics. Peacetime uses of styrene-based plastics expanded rapidly, and polystyrene is now one of the least expensive thermoplastics on a cost-per-volume basis. In this experiment, we will use three properties to identify a liquid substance: solubility, density and boiling point.. A great variety of catalysts have been investigated for the production of C 2 H 4 by the oxidative dehydrogenation of ethane (ODE) in the last decade [2,3]. Finally, styrene is distilled away from the tars and polymers under vacuum to keep the temperature as low as possible. The reactors are run at the lowest pressure that is safe and practicable. Ethylbenzene, Styrene Monomer, Acrylonitrile Butadiene Styrene and Polystyrene technologies Badger Ethylbenzene (EBMaxSM), Styrene, ABS, ... acceptance as the worldwide standard for EB production.
