UNIVERSITY OF SAN CARLOS DEPARTMENT OF CHEMISTRY NAME: Maniwang‚ Ma. Aiza C. DATE: March 21‚ 2011 COURSE: BS Chemistry II APPROVED: ___________ PREPARATION OF AZO DYES ABSTRACT In this experiment‚ the azo dyes p-nitrobenzene azoresorcinol and methyl orange were prepared by the azo coupling reaction. The p-nitrobenzene azoresorcinol dye was prepared from p-nitroaniline and resorcinol. The diazonium salt formed was from the reaction of the cold solution of dissolved p-nitroaniline

ranged at 117.8-125.2C as shown in Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure

They are commonly referred to as "surgical alcohol". Used to disinfect the skin before injections are given‚ often along with iodine (tincture of iodine) or some cationic surfactants (benzalkonium chloride 0.05–0.5%‚ chlorhexidine 0.2–4.0% or octenidine dihydrochloride 0.1–2.0%).

condensation reaction. This consists of one mole of acetone and two moles phenol while bubbling hydrogen chloride throughout the entire variety. In this process‚ acetone and phenol implants in a reactor with a cation exchanger. The alteration to Bisphenol A happens at around 75°C. The resulting mixture then passes in a concentrator‚ where it releases all acetone and water‚ under decreased pressure. BPA crystallizes out washed with phenol and distilled out under diminished pressure and cooled. The industry

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate
