Relative Reactivity of Anilines Abstract: Various Anilines were tested with Br2/HBr solution‚ the products were crystallized and melting points attained to verify relative reactivity. My assignment‚ 2‚4-Dibromoanisol‚ was prepared in a yield of 52% with a melting point of 55-58 C . Reaction: Mechanism: Procedure: Anisole (0.35mL‚ 0.0378mol) was obtained and placed in a pre-weighed 25 mL round bottom flask‚ along with 2.5 mL of glacial acetic acid and a magnetic stir bar. Then the

Air Conditioning Systems An air conditioning‚ or HVAC&R‚ system is composed of components and equipment arranged in sequence to condition the air‚ to transport it to the conditioned space‚ and to control the indoor environmental parameters of a specific space within required limits. Most air conditioning systems perform the following functions: 1. Provide the cooling and heating energy required 2. Condition the supply air‚ that is‚ heat or cool‚ humidify or dehumidify‚ clean and purify‚ and

influenced the formation of the Petristan state. Consequently‚ The Petristan State Archaeological Survey has selected 5000 sherds from eighteen probable sites by random sampling techniques in effort to investigate the proposed postulation. In principal‚ relative dating method of seriation has been implemented for deriving a chronological order of these assemblages for better understanding of any prominent flow of Paratha Valley influences to the initial development of Petristan state.

Deterioration occurs because of some factors that give an impact to the archival materials. The factors are divided into two groups which is inherent factor and external factor. Compare to external factor‚ inherent factor is the biggest responsible for deterioration of archival materials. According to M.C.
