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%. In this communication, the literature pertaining to the self–condensation of ketones to yield dimer, trimer and tetramer products and also the condensation of various ketone molecules with aldehydes to produce ketone–aldehyde resins are analyzed and a state–of–the–art review is written. 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. Then, 20 mL of Wij’s solution was added into the resin, solution, and the whole mixture was kept in the dark for, iodide solution was added into the flask and the mixture was, titrated with sodium thiosulfate solution. Therefore, all the experiments were performed for a, Moisture Content and Average Molecular Weight, The moisture content of the solid resin was determined by, using the Karl Fisher Instrument. To study, the effect of reaction time, a set of experiments were carried, out for different time durations at constant operating con-, ditions, and the results are shown in Table, show that for a fixed ketone-to-alkali ratio and fixed tem-, perature, if the reaction time is increased, then the degree, of polymerization increases and consequently softening, point and hydroxyl value of the product increases. condensation of alpha, beta–unsaturated ketones. Incepted in the year 1993, Bharat Resins Limited is engaged in manufacturing, supplying and exporting superior quality synthetic resins, epoxy resins and varnishes. Base–catalyzed intermolecular condensation of alpha, beta–unsaturated ketones. The material is again carefully dried and ground when it is ready to be molded under heatand-pressure to form a hard-dense substantially infu'sible article. Originality/value The reaction in this or steam and the reaction may be carried out either'by mixing all the ingredients together in complete amount required or the method may be varied by adding the formaldehyde or aldehyde reagent gradually to the acetone or other ketone or vice versa. Preparation of aqueous ketone resin or ketone, dispersions, and production of surface–coating binders, US Patent. The study confirmed that KOH offers better quality product than NaOH. In coating, technology, cyclohexanone resins are mainly used to, improve the intensity, glossiness, and hardness of coating, material. Acetone was polymerized under the action of NaOH, NaOEt or KOH in ethanolic or methanolic solutions at a molar ratio acetone/base ranging from 1.5:1 to 12:1 to give a liquid resin.

Preparation and application; Test procedures; PIGMENTS FOR PAINTS, INKS AND PLASTICS DEVELOPMENTS IN RESINS … From the overall investigation, it can be concluded that the in-house-developed ketonic resin products can be a suitable substitute of alkyd, ketone−aldehyde or phenol−aldehyde resins for paint and coating applications.
