In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
Phenol-formaldehyde resins (P/F ratio 1/1.75) were synthesized using paraform and 97% phenol as reactants under the influence of a basic catalyst (0.5 mole catalyst/mole phenol). Three catalysts (i) sodium hydroxide, (ii) barium hydroxide, (iii) triethylamine were used to monitor the effect that the chemical nature of the catalyst had on the course of the reaction.
