4-Bromoanisole is the organobromine compound with the formula CH 3 OC 6 H 4 Br. It is colorless liquid with a pleasant smell similar to that of anise seed. It is one of three isomers of bromoanisole, the others being 3-bromoanisole and 2-bromoanisole. It is the precursor to many 4-anisyl derivatives.
Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites.
2,4,6-Tribromoanisole (TBA) is a chemical compound that is a brominated derivative of anisole. It is one of the chemicals responsible for cork taint. [2] Tribromoanisole is a fungal metabolite of 2,4,6-tribromophenol, which is used as a fungicide. It can be found in minute traces on packaging materials stored in the presence of fiberboard ...
The radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. [4] The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule) where it absorbs more water. Most of the seed is stored energy so nutrients are not essential ...
Adsorption is present in many natural, physical, biological and chemical systems and is widely used in industrial applications such as heterogeneous catalysts, [9] [10] activated charcoal, capturing and using waste heat to provide cold water for air conditioning and other process requirements (adsorption chillers), synthetic resins, increasing ...
Absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter the liquid or solid bulk phase of a material. This is a different process from adsorption , since molecules undergoing absorption are taken up by the volume, not by the surface (as in the case for adsorption).
VSA typically draws the gas through the separation process with a vacuum. For oxygen and nitrogen VSA systems, the vacuum is typically generated by a blower. Hybrid vacuum pressure swing adsorption (VPSA) systems also exist. VPSA systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas.
