The family of styrene resins generally breaks down into polymer styrene and copolymers AS and ABS. All these are thermoplastic resins manufactured with styrene, one of the petrochemicals, as main feedstock. Such styrene ...

The basic catalyst, dry TiC 13, 1/3 A1C13 is blended and milled with triphenylphosphine oxide (10:1.67 molar ratio) to form a fixed particle size. Fresh and recycle propylene plus catalyst is fed to the first of the polymer ...

Ethylene is compressed to a reaction pressure of 1 500 bar, initiated with air or oxygen and passed to an autoclave reactor. This has an L/D ratio of 10/1. Lower conversions of 15-20 percent per pass at residence terms ...

Pressurised air at 3 bar is mixed with o-xylene vapour and is fed to a packed tube reactor. There are 32 tonnes of air per tonne of xylene. This keeps the mixture outside the upper explosive limit. The product gases ...

Pentaerythritol was initially developed as a raw material to make explosive. But, later, this was mainly used in the manufacture of alkyd resins. The production of pentaerythritol showed rapid growth due to the tremendous ...

Caprolactam and process water (up to 10 percent) are charged to an autoclave reactor. The vessel is purged with nitrogen, heated to 2100C and is pressurised to a maximum of 18 bar when polymerisation occurs. The pressure is ...

Recycle and fresh methanol are vapourised and mixed with air, and superheated to 100oC-l30oC. Hot gases pass to the converter after mixing with by-pass air and steam. The converter contains granules of silver catalyst ...

Ethylene is combined with high purity oxygen with a molar ratio of ethylene to oxygen of 3.33. Methanol ballast is maintained at 45 percent concentration. This mixture at 2200C is fed to a tubular reactor at 17.2 bar ...

There are two reaction sections in this process. In the first section, high purity ethylene and chlorine (99+ percent) react in a liquid-phase, non catalytic reactor at about 11 bar and SOOC. In the second section, ...

DEP, with the common name Trichlorfon, has an active ingredient, dimethyl 2, 2, 2-trichloro-l'hydroxyethyl phosphonate. It was first introduced in 1952 by Bayer AG under the trade mark "Dipterex ", DEP is an insecticide ...
