The synthesis involves the condensation of acetone with phenol:

This was done by mixing the two reactants with NaOH and ethanol, then allowing the reaction to sit for thirty minutes.

The purpose of this experiment was to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde.

The crystals were then washed with water three times and recrystallized using ethanol.

Biomass and waste gasification are also being used to produce syngas for a wide range of downstream products, including methanol synthesis. In some of those applications, the initial methanol product is being used to synthesize ethanol (ethyl alcohol), which is then used as a fuel additive with gasoline.

can be used to produce a syngas with the proper H2 to CO ratio. Coal gasification, followed by the water shift reaction, is used worldwide to produce syngas which is then converted downstream to methanol. Coal gasification has become a major syngas production process for the manufacture of methanol in China, which has more than 50 such plants in operation, with dozens more in construction or planning. Even more plants are in operation, with dozens more in construction and planning (in China and Mongolia), using the methanol to produce valuable downstream products. These coal gasification plants producing methanol, as well as the integrated Methanol-to-Olefins (MTO) and Methanol-to-Propylene (MTP) plants, have allowed China and Mongolia to economically produce a wide range of downstream products, replacing expensive or scarce natural gas and petroleum-based feedstocks.

The second reaction above uses catalysts to assist in the reaction to combine the single CO and the two H2 molecules to form the desired methanol product. This reaction is exothermic, creating a significant source of heat that is typically used elsewhere in the manufacturing plant to generate steam and/or electricity. The ratio of H2 to CO is specific for different downstream processes (see and ). For methanol synthesis, the ratio is 2:1. Fortunately, the steam methane reforming step shown in Reaction #1 above produces exactly the ratio (2:1) required for methanol synthesis.

Acetone peroxide - Sciencemadness Wiki

Methanol is primarily used in making other chemicals. About 40% of methanol produced is converted to formaldehyde, which is then converted to other products such as plastics, paints, explosives, and resin-based adhesives used in the manufacture of plywood and wood products.

Methanol, or methyl alcohol, is the simplest alcohol, with the chemical formula CH3OH (often written as “MeOH”). It has also been known as wood alcohol, wood spirits, spirit of wood, and wood naphtha, because it used to be produced via pyrolysis of wood. This “spirit of wood” was a key ingredient in Eastman’s process for manufacturing Kodak photographic film. Today, methanol is a widely used commodity chemical, which is used directly, as well as a feedstock for the production of a wide range of other alcohols, liquid fuels, chemicals and plastics

The strategy described by Corey and Enders entails generation of the anion by BuLi, addition of the aldehyde or ketone to yield the -hydroxy hydrazone, and oxidative cleavage using NaIO in methanol at pH 7 to regenerate the carbonyl compound.

Benzyl methyl ketone; Methyl benzyl ketone; Phenyl-2-propanone

Acetone behaves very differently in the presence of halogens in basic solutions. Rather than becoming halogenated, methyl ketones are oxidized to a carbonylic acid in which the methyl group has been removed. The reaction of acetone with excess iodine (I2) and sodium hydroxide (NaOH) yields sodium acetate, Na+ : [H3CCO2]-, and triiodomethane (), CHI3, an antiseptic agent commonly used in hospitals.

Organometallic reagents, such a or organolithium reagents, can also be used as nucleophiles to react with acetone. For example, R3C-MgBr, a Grignard reagent, can react with acetone to produce the tertiary alcohol R3C-C(OH)(CH3)2. The formation of new carbon-carbon bonds in such a manner is critical to the synthesis of many complex organic molecules.

Ketones can be used in reactions, although they are less reactive than aldehydes in this regard. Aldol condensation reactions occur when the carbanion carbon of an enolate reacts with the carbonyl carbon of a ketone or aldehyde, forming a new carbon-carbon bond. Acetone can react with itself, to produce the ,-unsaturated ketone 4-methyl-3-penten-2-one, or with other carbonyl compounds.
