Nitration of Methyl Benzoate: A Lab Report

Nitration of Methyl Benzoate: A Laboratory Report Abstract The major aim of the experiment was to substitute the hydrogen atoms on the methyl benzoate ring with a nitro group to obtain a pure product of methyl 3-nitrobenzoate after recrystallization. Nitration of Methyl benzoate follows the principles of an electrophilic aromatic substitution reaction. As such, the attachment of the nitrogen group depends on the type of pre-existing functional groups on the ring. In this case, the […]

Synthesis of Dibenzalacetone via Aldol Condensation Reaction Mechanism

Abstract The experiment aimed at synthesizing Dibenzalacetone through aldol condensation reaction by reacting an ethanolic mixture of benzaldehyde and acetone with sodium hydroxide. The product targeted in the practical is crystals of Dibenzalacetone, which are later filtered and separated from the mixture as the residue, washed, dried and recrystallized using ethanol and water solutions. The experiment proceeds with respect to the reaction below. Benzaldehyde             acetone                                                Dibenzalacetone Figure 1: A structural synthetic route for […]

Investigating microbial transfer on desktop keyboard

Abstract Computers have been known to play a role in the spread of nosocomial infections, whether they are used in medical or non medical facilities, as they are known to harbour microorganisms. Microorganisms in the home, offices and in health facilities are deactivated using surface cleaners and disinfectants. An investigation is carried out to study the transfer of microorganisms such as Staphylococcus aureus, Enterobacter and Enterococcus on computer keyboards, and the efficacy of disinfectants against […]

Investigating microbial transfer on desktop keyboard

Results             Bacterial species wereisolated from computers located in different places in the University. This isolated 21 different bacterial species which were later disinfected to test on the efficacy of the disinfectants against the microbes commonly found on computer key boards. Of the 21 colonies identified, only a few were included in the write up as the rest were too few to count. The results show that key boards with multiple users such as those […]

Investigating microbial transfer on desktop keyboard Abstract Most computers both in medical and non-medical institutions tend to harbor different kinds of microorganisms such as Staphylococcus aureus, Enterococcus, and Enterobacter. As such, these computers are known to be associated with hospital-acquired infections. Offices, homes and health centers have taken upon themselves to use surface cleaners and disinfectants to deactivate and kill these microorganisms, hence reducing the chances of nosocomial infections. The research is designed to find […]
