Reaction enthalpy was experimentally calculated and an endothermic reaction was determined (ΔHr° = 59.2 kJ/mol). At this point the reaction was'stopped byaddition of dilute sulphuric acid until the mixture showed a slightly acid reaction. Cyclohexanone resin is compatible, many other coating materials such as alkyd resin, vinyl, chloride copolymer, cellulose nitrate, aromatic and aliphatic, epoxy resins, and phthalate plasticizers. Mark–Houwink correlation was used to predict molecular weight of the resins. Probable dimeric (n ¼ 1) and polymeric (n ! The object ofthe invention is to produce various types of resins which are soluble in J available organic solvents and which generally speaking when soluble are fusible and suited for use in the manufacture of shellac substitutes, varnishes, coating compounds, polishes and other purposes to which resins of this general character may be applied in the arts. The preexponential factors and the activation energies of the kinetic constants are given.

Still another method which is advantageous on account-of low-cost of handling 'is mixing'on heated rolls. It was then readily soluble in acetone and was fusible, melting sligl itllky e resin was then heated to 105 C; for about fifteen hours and was then still slightly fusible but was insoluble in all ordinary solvents such as acetone, alcohol, toluol and mixtures of these solvents also insoluble in. Moreover, experimental data from other authors in literature can be also reasonably well predicted with the model developed. With the, increase of temperature, both the reaction rate constant, and catalyst activity increases and hence the degree of poly-, merization increases.

The resins are considered to be too brittle for use as the Originality/value In the study, reaction time was varied from 10−17 hrs, reaction temperature was varied from 130−150 °C, catalyst concentration was varied from 20−40%. The ketonic resin can be used as a substitute of phenolic resins which are prepared from more hazardous materials monomers such as phenolic and aldehyde compounds. The foregoing resins may be prepared in so far as possible simultaneously with the production of the ketone resin or may be separately prepared and dissolved in the acetoneor other ketone employed and the latter subjected to resinification. This leads to brilliant gloss even at high pigmentation. Acetone resins (PCA) obtained both with Bronsted acids (PCA-B), Lewis acids (PCA-L) and alkaline catalysts (PCA-A) can be easily halogenated up to certain degrees of saturation. Hydroxyl value, iodine value, solubility, rheology, gel permeation chromatography (GPC), thermogravimetric analysis (TGA), scanning electron microscope (SEM) and the X-ray diffraction (XRD) analysis were carried out to characterize the product properties. Based on the present study, it is concluded that the in−house developed resin from cyclohexanone can be used for coating applications. While I prefer to employ aqueous formaldehyde it is also possible to carry out the reaction.

The effects of reaction parameters, such as reaction time, temperature, catalyst concentration and monomer, Synthetic resins are used for various applications including in paint industry to improve the glossiness, adhesiveness, hardness, and dryness of paints. The hydroxyl value of the liquid products was less than 90 mg KOH/g of sample and the product is not suitable for coating applications due to the presence of significant amount of dimer, trimer and unconverted monomer. In general, methyl-cyclohexanone resins are softer and more plastic in, of ketones catalyzed by aluminum oxide. Ketonic Resin is a good substitute for natural alcohol soluble resins like shellac. The number-average molecular weight of the developed resins was in the range of 450-1150. It has been further observed that the adhesive strength of the solid resins is comparable with the commercial fivistick material. The results suggest that the self-polymerization of cyclohexanone mainly depends on alkali concentration, reaction temperature, and reaction time. y. a iliquidmfm light yellow color which could heusedasa yarnish.

From the literature, survey, it has been observed that there is no information, available regarding the preparation and analysis of a ke, resin. It was, also observed that for the reaction time less than 12, mass obtained was partly solid and partly high viscous, liquid. The product is a pale yellow to light yellow solid having solubility in aromatic hydrocarbons, alcohols, glycols, esters, ketones, chlorinated hydrocarbon and so on but is insoluble in water. Reactive distillation can be advantageously used to enhance the selectivity toward the desired product. Synthetic resins are extensively used in paint industry to improve the adhesiveness of paints. The effect of reaction parameters such as reaction time, temperature, and catalyst loading on hydroxyl value, iodine value, solubility, and average molecular weight of products was investigated. The liquid resin was obtained with a maximum yield of 60% over initial acetone and was always accompanied by variable quantities of isophorone. This chapter includes the manufacturing process of the product, chemical reactions, and material mass balance for the product. With the present form of resin (at least with the more sensitive types) articles may be cured to a sufficient degree in one or two minutes in many instances. As caustic soda or caustic potash is sometimes objectionable owing to a stro alkaline reaction sodium sulphite may used in some cases. Regression models were developed to predict the optimum conditions for obtaining a desired quality of resin. As the ketone-to-alkali ratio decreases, the degree of poly-, merization increases, which leads to an increase in the, hydroxyl value and softening point and a remarkable, decrease in solubility along with minor decrease in acid. A remarkable influence of water content on the cyclohexanone conversion profiles was observed. As the reaction progressed the solution which was light in color became a light brown and increased somewhat in viscosity. Kinetic of. disclosed in the US4644028 patent (Fischer et al., The patent claims that alkali-catalyzed self-conde, presence of an alcoholic medium. sition of raw materials and operating parameters. he heavy At this point the viscous resin solution is very soluble if not freed -from the acetone associated with it and may be very readily diluted at-this stage with further quantities of acetone or other suitable solvent including benzol and other hydrocarbons and a small amount of a suitable ,acid such as acetic or hydrgchloric acid added to precisely neutralize the alkali. The developed ketonic resins were thermally stable up to the temperature of around 200 °C and the stability was comparable with the studied phenol–formaldehyde and alkyd resins. Ketones and aldehydes can be converted to resinous products by condensation reaction. of 20% alcoholic caustic soda. Different varieties of ketonic resin such as Laropal K80, MS2, AW2, and Ketone Resin-N etc. may be somewhat viscous due to ,dissolved resin and especial care should be taken to avoid'too vigorous reaction and loss of material by foaming over. The solubility of the product in mineral turpentine oil, (MTO) was checked by dissolving it into a fixed quantity.
