Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

Pigments were first extracted from tomato paste by a 50/50 mixture of acetone/hexanes; these miscible molecules act together as one organic solvent. Pigments choose the organic layer over the tomato paste with water‚ which allowed for their extraction. K2CO3 is an ionic base that was added to deprotonate the citric acid. The ionic product of the reaction in figure 3 now prefers the aqueous layer‚ which serves to wash the pigments of the acidic impurity. Saturated NaCl pulls any water into the

Acetone is an extremely popular solvent that is used in rubber‚ resin‚ plastics‚ lacquers‚ varnishes‚ and rubber cements. It is also used in the creation of fats‚ oils‚ and waxes where is a primary component. Acetone has many uses in modern technology including those that relate to the medical field and various domestic uses. It is a very important organic compound found in everyday life‚ but it is also a toxin and can be an extremely dangerous environmental pollutant. Acetone has many valuable

Background of the Study Familiar household uses of acetone are as the active ingredient in nail polish removers and as paint thinner. Acetone can also be used for medical and cosmetic uses‚ such as applying acetone with alcohol for acne treatments to peel dry skin. It can also remove residues from glass and porcelain and it can also remove super glue from the skin. Perhaps‚ acetone is very useful in our everyday lives. Acetone is also known to remove ball pen marks on fabrics and clothings

experiment is to see if we can recycle polystyrene using acetone. If this is possible‚ this can be used to help improve our environment since polystyrene itself is not biodegradable. Hypothesis: I hypothesis that polystyrene‚ mainly known as styrofoam‚ can be recycled using acetone. This cost efficient and easy method will not only motivate both individuals and industries to recycle but also improve the state of our environment. Materials: 100% acetone nail polish remover 3 small containers 4 Styrofoam

Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z
