Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

VAPORIZER:2-butanol feed is vaporized at 107.50C using reaction products. Heat load on vaporizer is ‚ Q = M x λ = 26017.91 x 557.43 kj = 14.5032 x 106 kj/hr Average Cp of reaction products = 2.3 KJ / Kg 0k 14.5032 x 106 = 26017.91 x 2.304 (642 – T) 22 T = 400 K FIRST SUPER HEATER:2-butanol vapors is to be heat4ed from 380.5 k to 573k . using flue gas which enters at 673 k & cools to 423k. Cp = 2.038 kj/kg k. Heat load on super heater‚ Q = M x Cp x (T2 – T1) = 26017.91 x 2.038 (573 – 380.5)

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

to read it and record the results. We measured the absorbance of most highly colored tube at wavelength of 360-500nm by using 20nm intervals. Then we repeated the absorbance measurement with less colored tube after we adjusted it to 0 absorbance (100%T) at each wavelength‚ in order to determine most reasonable wavelength which was 460nm for 2-3 experiment.
