One specific non-solvent application for Diacetone is as a chemical intermediate in the production of diacetone acrylamide as is having hydroxyl and carbonyl group in the same molecule.

OTHER APPLICATIONS of Diacetone Alcohol
Diacetone alcohol is more suitable for use in applications as a component of gravure printing inks, with proving favorable flow and leveling characteristics. 
Other applications for Diacetone include metal cleaning compounds, degreasers, stripping aids for textiles, and gum and resin removers in automobile carburetor cleaners.

Reactivity Profile    
Acetyl bromide reacts violently with alcohols or water.
Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. 
Example: An explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. 
Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. 
Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid.
Alkyl hypochlorites are violently explosive. 
They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. 
Chlorine plus alcohols would similarly yield alkyl hypochlorites. 
They decompose in the cold and explode on exposure to sunlight or heat. 
Tertiary hypochlorites are less unstable than secondary or primary hypochlorites 
Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. 
Such reactions in the absence of solvents often occur with explosive violence.

APPLICATIONS
-Diacetone alcohol can be used to make metal cleaner, wood preservative, photographic film and drug preservative, antifreeze, hydraulic solvent, extraction agent and fiber finishing agent.
-Diacetone alcohol is widely used as a solvent for electrostatic spray painting, celluloid, nitrocellulose fiber, fat, grease, wax and resin, etc.

First identified by Heintz, one standard laboratory preparation of DAA entails the Ba(OH)2-catalyzed condensation of two molecules of acetone.
Diacetone Alcohol undergoes dehydration to give the α,β-unsaturated ketone, mesityl oxide:
Hydrogenation of mesityl oxide gives the industrial solvent, methyl isobutyl ketone ("MIBK"). 
Hydrogenation gives hexylene glycol. 
Condensation with urea give diacetone-monourea.

Diacetone alcohol is an organic solvent with medium boiling point.

Solvent is a substance, usually a liquid, that acts as a dissolving agent or that is capable of dissolving another substance. 
In solutions of solids or gases in a liquid, the liquid is the solvent. 
In all other homogeneous mixtures (i.e., liquids, solids, or gases dissolved in liquids; solids in solids; and gases in gases), solvent is the component of the greatest amount. 
The minor proportion substances are called solutes. 
Diacetone alcohol offers several functions during a chemical reaction. 
Diacetone alcohol solves not only the substance that reacts with another one to produce a new set of substances (reactant) but also the compound that supplies the molecule, ion, or free radical, which is considered as the attacking species in a chemical reaction (reagent). 
Diacetone alcohol is conductive to collisions between the reactants and reagents to transform the reactants to new products. 
Diacetone alcohol also takes roll of temperature control, either to provide the energy of the colliding particles for speedy reaction and to absorb heat in exothermic reaction. 
The appropriate solvent should be selected based on the inactivity in the reaction conditions, dissolving the reagents as well as reactants, appropriate boiling point and easy removal at the end of the reaction.

Di-Acetone Alcohol applications include: 
solvent for nitrocellulose, cellulose acetate, various oils, resins, waxes, fats, dyes, tars, lacquers, dopes, coating compositions, wood preservatives, stains, rayon and artificial leather, imitation gold leaf, dyeing mixtures, antifreeze mixtures, extraction of resins and waxes, preservative for animal tissue, metal-cleaning compounds, hydraulic compression fluids, stripping agent (textiles), laboratory reagent.

Polarity
The most common solvent is water. 
Other common solvents which dissolve substances that are insoluble (or nearly insoluble) in water are acetone, alcohol, formic acid, acetic acid, formamide. 
BTX, carbon disulfide, diemthyl sulfoxide, carbon tetrachloride, chloroform, ether, tetrahydrofuran, furfural, hexane and turpentine. 
They may be classified as polar and non-polar. 
Polar solvents, like water, have molecules whose electric charges are unequally distributed, leaving one end of each molecule more positive than the other. 
Usually polar solvent has O-H bond of which water (HOH), (CH3OH) and acetic acid (CH3COOH) are examples. 
Propanol, butanol, formic acid, formamide are polar solvents. 
Dipolar solvents which contain a C-O solid bond without O-H bond are acetone [(CH3)2C=O], ethyl acetate (CH3COOCH2CH3), methyl ethyl ketone, acetonitrile, N,N-dimethylformamide and diemthyl sulfoxide. 
Nonpolar solvents, like carbon tetrachloride (CCl4), benzene (C6H6), and diethyl ether ( CH3CH2OCH2CH3), have molecules whose electric charges are equally distributed and are not miscible with water. 
Hexane, tetrahydrofuran and methylene chloride are non-polar solvents. 
Polar solvents are hydrophilic but non-polar solvents are lipophilic. 
Polar reactants will dissolve in polar solvents. 
Non-polar solvents dissolve non-polar compounds best. 
Oil and water don't mix but separate into two layers. 
There are three measures of the polarity as "dipole moment", "dielectric constant" and "miscibility with water". 
Though low dipole moments and small dielectric constants indicates non-polar solvents, sharp boundaries between polar and non-polar solvents are not available. 
The polarity reflects the balance between a polar component (OH) and a non-polar hydrocarbon component, existing in the same molecule. 
If hydrocarbon character increases relatively, the polarity decreases. 
On an operational basis, solvents that are miscible with water are polar.

Polar Protic and Dipolar Aprotic

Protic refers to a hydrogen atom attached to an electronegative atom. 
Protic solvents can donate an H+ (proton) since they contain dissociable H+, such as hydrogen attached to oxygen as in a hydroxyl group, nitrogen as in a amine group. 
Examples are water, methanol, ethanol, formic acid, hydrogen fluoride and ammonia. 
Aprotic solvents don't has O-H bond but a C=O bond typically. 
Examples are acetone [(CH3)2C=O] and ethyl acetate (CH3COOCH2CH3). 
Polar protic solvents are useful in SN1 reaction, while polar aprotic solvents are SN2 reaction.
