Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction

Part 2 Case 3 – E Question (MICRO ISSUES ) 1. should those who developed the Brita campaign have investigated whether the Filters could be recycled before they were public with the Effort ? 2. Should news journalist investigate campaigns of this sort and write about what they find? 3. How does this effort at corporate social responsibility seem like or unlike others – for example ‚ turning in the tops of yogurt containers in exchange for corporate donation to breast cancer research ?

An experiment was run to determine which enzyme (pectinase‚ and cellulase or combinations of the two enzymes) maximizes juice production and would be most cost effective. The proposed hypothesis was if the enzyme‚ pectinase‚ is added to apple juice‚ then the more juice will be extracted than if cellulase were added because pectinase holds the cell wall together and if it is separated apart from each other‚ then the more juice would be able to flow out. The experimental data show that during the ten
