Methanol

Borneol was the minor product. This is a reduction reaction, where the ketone on the Camphor is reduced to form two products with secondary alcohols. First, 0.25 grams of Camphor was obtained and added to a 50ml flask and mixed with 1.5 ml of methanol. Second, 0.25 grams of Sodium Borohydride was added to the reaction mixture and the reaction mixture was boiled for 2 minutes. Third, the mixture was left to cool and 10ml of water was added to it. The reaction mixture was then filtered…

directly above the pepper using scissors/shears (“How to Grow Chili Peppers Indoors”). Capsaicinoid chemicals are commonly extracted from the peppers to add spice and heat to chili powder (“Capsaicin”). Some solvents used during extractions are Acetone, Methanol, and Ethanol and these solvents must not have large quantities of water. This extraction process is completed using a piece of laboratory equipment called a Soxhlet Extractor. Soxhlet Extractor devices use less solvent during extractions…

there is a thin layer of ethanol above the alumina, about 2-3 mm, drop three drop of a 5% methylene blue and fluorescein and 95% ethanol into the column, then pour more ethanol into the pipette while collecting the drippings in a beaker. When all the methanol blue is out of the pipette, pour water into the pipette to collect the fluorescein in a…

fuels. There are of course disadvantages to the use of alternative fuel driven cars. Vehicles that run on compressed natural gas will cost $2,500-5,000 more than a conventional car (Derr, 1994). Methanol does not offer convincing benefits over standard reformulated gasoline. Research shows that methanol does not offer any environmental benefits over reformulated gasoline and it is considerably more expensive Table…

[16]. Sixteen formulations were prepared according to the experimental design shown in Table 3.Accurately weighed quantities of drug, soya lecithin, and edge activators (surfactant) in various ratios as listed in Table 3 was dissolved in chloroform: methanol (2:1) in 250 ml round bottom flasks. The solvent mixture was evaporated at optimized temperature under reduced pressure at 80 rpm using rotary vacuum film evaporator (Heidolph loborata 4011 digital, Switzerland). After complete evaporation…

sweeteners, many of which are artificial sugar substitutes containing no natural sugars, such as saccharine and aspartame. Aspartame, which is commonly used as an artificial sweetener, is made of three chemicals, Phenylalanine, Aspartic Acid, and Methanol, and Neotame. Aspartame can have a negative effect on your nervous system (brain) so much so that Aspartame is categorized as a Neurotoxin (brain poison) ( Chase, C., 2013). The sweeteners work by blocking receptors on the…

Telangana ABSTRACT In the present study , antiepileptic effect of the methanolic extract of the leaves of Citrus Grandis was evaluated by hand limb extension induced by chemically induced seizures in mice models.Two different doses were selected .The methanol extract of the leaves of Citrus Grandis (150, 200 mg/kg, i.p.) was studied for its antiepileptic effect on caffeine induced seizures in mice. Citrus grandis (150 and 200 mg/kg) significantly reduced the duration of seizures induced by…

Introduction The purpose of this lab was to identify the lipids in an egg yolk and to identify the amount of lipids in milk [1]. To extract the lipids from the egg yolk, the egg yolk needed to be combined with an organic solvent such as a mixture of CHCl3/MeOH. An organic solvent was needed to carry the extracted lipids up the TLC plate because the plate was polar, due to the presence of silica gel (silanol groups). To compare relatively similar lipids to the ones found in the egg yolk, the egg…

Biodiesel which is an alternate fuel, is produced…

Radioactivity past paper assignment Question 1: In the fridge, from a previous experiment, there is a 50 mM [U-14C] glucose solution. A 20 uL aliquot was counted and gave 200 000 dpm. What is the specific activity of this preparation? 20 uL = 200 000 dpm (divide both sides by 20) 1 uL = 10 000 dpm Glucose = 50 mM = 50 mmol / uL = 50 umol/ uL = 50 nmol / uL Therefore in one uL = 50 nmol/ uL = 10 000 dpm (divide both side by…
