the absorbance of the liquids with the different solvents. Solvent Results from colorimeter 0.001 Acid (Hydrochloric) 0.358 Ethanol 0.132 Hot water 0.984 Cold water-distilled water (control) 0.057 CONLUSION: The results show that hot water gave the highest average absorbance reading from the colorimeter‚ followed by hydrochloric acid‚ ethanol and cold water‚ in descending order of absorbance. The absorbance of the solvent that was hot water affected the most the permeability

Experiment 1: Bromination of Acetanilide1 Precautions: Ethanol is flammable Sodium hypochlorite is an oxidizing agent and releases toxic fumes (handle in fume hood) Acetic acid is corrosive‚ harmful if inhaled‚ flammable and can cause burns (handle in fume hood) Gloves are recommended to avoid chemical contact with skin Reaction Scheme: Conversion of acetanilide to p-bromoacetanilide Procedure: To a 125 mL Erlenmeyer flask containing a mixture of 95% ethanol (6 mL) and acetic acid (5 mL)‚ dissolve acetanilide

Discussion & Error Analysis: By examining the unknown alcohol’s H NMR spectra‚ it can be deduced that the alcohol is 1-(3-methoxyphenyl)ethanol. There are three peaks that have a shift of ~7.0-7.5‚ one with integration values of 1‚ 2‚ and 1.This shows that the alcohol is a meta-substituted benzene ring. The singlet peak with a chemical shift of~ 4.7 ppm with an integration of 1 is from the hydrogen on the OH group. The peak at ~ 1.7 ppm corresponds to the hydrogen of the carbon that is attached

Extraction of Ethanol” from Jackfruit Pulp (Artocarpus heterophyllus) as an alternative source of ethanol. Statement of the Problem Generally‚ this study aims to determine if jackfruit pulp (Artocarpus heterophyllus) can be a source of ethanol. Specifically‚ this study aims to answer the following questions: 1. Is there a significant relationship between the percent yield of ethanol and the different lengths of fermentation of the jackfruit pulp (Artocarpus heterophyllus)? 2. Is there a significant

distillation‚ the percent ethanol and percent loss of 15 mL of vodka was computed. The calculations were supported by a flammability test. With the distillation process reaching 100oC‚ 6.0 mL of distillate was collected. The determination of ethanol from the distillate was conducted through the flammability test‚ which resulted to 4.5 mL. After the needed computations‚ it was measured that the percent ethanol was 30% and the percent loss was 26%. Keywords: simple distillation‚ percent ethanol‚ percent loss

DCS ULO Relatieve respiratie Ethanol!! 0 % O2 21 TM Dynamic Control System With the DCS™ system the lowest possible oxygen value during storage is sought instead of the ‘safe’ 1% oxygen. When the apple starts to ferment automatically a permanent minimal flow of oxygen is supplied. By this method apples are stored in the best possible way. O2 / CO2 CONTrOL SENSOrS O2 CO2 Ethanol New for DCS™ With special systems alcohol formation is determined manually by e.g. cutting apples into pieces

and water. In this experiment you will determine the molar heat of combustion of methanol‚ ethanol‚ 1propanol‚ 1butanol; and 1pentanol. Experimental Procedure Equipment * Electronic Balance ±0.01g * Measuring Cylinders ±1 mL * Aluminium Can * Cotton Wool * Theromometer ±0.5C * Retort Stand and Clamp * Spirit Burner containing alcohol sample * Alcohols (methanol‚ ethanol‚ 1-propanol‚ 1-butanol‚ 1-pentanol) Safety The alcohols are highly flammable.

An alcoholic beverage is a drink containing chemicals from the alcohol family. Mostly ethyl alcohol (ethanol‚ EtOH)‚ other alcohols are usually present only in small quantities‚ notably consumable t-Amyl alcohol (t-Amylol‚ t-AmOH) which is about 20X more potent than ethanol‚ and hazardous methanol with much weaker sedative effect than ethanol‚ thus are not prohibited by law or regulated by taxation in most if not all countries. However‚ alcoholic beverages are divided into three general classes for

LAB OF ENTHALPY CHANGE IN COMBUSTION Objective: Determine the Enthalpy change of combustion ΔHc of three different alcohols. Methanol‚ Ethanol and Isopropilic acid. Procedure: 1. Fill the spirit micro burner with Ethanol and weight it 2. Pour 100 cm3 of water into the aluminum cup 3. Arrange the cup a short distance over the micro burner 4. Measure the temperature of water 5. When the temperature of the water has risen by 10°C‚ record the temperature. 6. Reweight
