The emulsion route to ABS involves the preparation of rubber latex - usually non-stereospecific polybutadiene. This latex is emulsified with styrene, acrylonitrile, and other components at a pH of 10-10.5 and 57-60oC. Residence ...

Alkylbenzene, a basic raw material used in detergents production, may be synthesized from alkanes or alkenes and benzene. The alkylation process chosen will depend on whatever raw materials are available, but all ...

Chemical grade propylene and fertiliser grade ammonia are fed with air to a fluid bed catalytic reactor operating at 420-480oC and 1.3 to 3 bar. High conversions are obtained in 5-10 seconds in an exothermic reactor. ...

In the direct hydration process, propylene and water are preheated and fed to a catalytic reactor, where isopropanol is formed. This reaction may be carried out in the vapour or liquid phase at pressures of 25-250 bar ...

Liquid phase oxidation of acetaldehyde occurs at 55-650C and 4.8-5 bar with manganous acetate as catalyst. If oxygen is used in place of air, the reaction temperature is raised to lO-80oC. The unreacted acetaldehyde and ...

Developing countries that export raw hides and skins often wish to make better use of this indigenous raw material - often one of the few resources available - by producing leather locally. However, building a complete ...

This profile deals with the production of pasta in a small factory capable of producing about 150 tonnes per year. The investment cost for this project is about $ 85,000 and 10 people would be employed. Pasta is commonly ...

The hides and skins of wild and domesticated animals have always been treated in some w~ to serve human beings as clothing. Leather is obtained if the treatment removes the hair and makes the hide or skin resistant to ...

The manufacture of pasteurized fruit juice has three stages: - Fruit treatment - Juice treatment - Product packaging Before details can be given, samples of the raw materials must be tested. The results of these tests ...

Wet milling of maize is a highly sophisticated and capital-intensive process. Pounding, the traditional small-scale method for the production of meal, on the other hand is very wasteful. This profile describes an alternative ...
