Distill dry solution using Hickmann still. When distillation complete‚ weigh the vial and calculate percent yield. Determine the infared spectrum of product using salt plate. Procedure: Day 1: First I weighed an empty 10mL flask with lid = 15.887g. Then I added the n-butyl

identify the unknowns by analyzing the physical properties on IR and NMR spectrums. The neutral solid was purified through recrystallization and the melting point range was determined to be 47.5oC to 48.9oC. The basic liquid was purified with simple distillation and the boiling point of 135oC was concluded. Through the analysis of IR spectrum of each unknown the structures for each unknowns were devised. An important peak for the solid unknown D was 1655.71 cm-1 (Ketone) and the peaks that were important

Examples which show this are “two stone windmills…one boiling house with seven coppers‚ one curing house and one still” and “permitting a single or continuous distillation process‚ as opposed to the double distillation process of the pot still”. Evidence was also documented in this piece‚ that is historical data and statistical data‚ such as “300 years old‚ and counting”‚ “the legal deed‚ dated 20 February 1703‚ complete with age-darkened

The book also described 107 methods and recipes for perfume-making and perfume-making equipment‚ such as the alembic (which still bears its Arabic name). The Persian chemist Ibn Sina (also known as Avicenna) introduced the process of extracting oils from flowers by means of distillation‚ the procedure most commonly

Lab Protocol #8 - Dehydration of 3‚3-dimethyl-2-butanol KEYWORDS: alkenes‚ E2‚ E1‚ carbocation stability‚ elimination A. Introduction. The dehydration of alcohols is an ELIMINATION reaction that is commonly used to form alkene molecules. The mechanism for the dehydration of alcohols consists of transforming the –OH functional group into a better leaving group by using a strong acid to protonate the alcohol. After –OH has been transformed into –OH2+‚ it becomes easier to break the σ-bond between the

Abstract This study entitled “Ethanol Production from Waste Banana Peelings” aims to produce an alternative way in producing energy. Banana chips‚ banana con hielo‚ banana cue and other Filipino delicacies made up of banana are some of our favorite foods. But after the consumption of the flesh‚ we are just throwing out the peelings as garbage. Our country today is facing two major problems‚ energy crisis and proper waste disposal. This study used waste banana peelings

The reason behind this is because the cyclohexene is highly flammable‚ so as to remove any unnecessary risk we used a heating pad. We then created our cyclohexanol mixture of cylcohexanol
