    摘要: The present invention is related to the use of a new conditioning agent for treating pelts for tanning. This conditioning agent consists in a composition of modified aldehydes, carboxylic acids or polycarboxylic acids and additives. The conditioning agent is used for replacing the steps of deliming and pickling in the pelts treatment. The action of the product can eliminate the step of basification when the tanning is made with chromium salts. The objective of the present invention is the use of a novel composition that can replace the steps of deliming, step 6, and pickling, step 8, described before for one just step called conditioning The proposed system, neutralizes the alkalinity and hence removes the solubility of Calcium from the liming operation attached in the pelt. The system described is obtained from functional aldehydes with the general formulation as following: The system comprises functional aldehydes to which are added a combination or just one of the following chemicals: mono, di, tri and polycarboxilic acids; anhydrides: fumaric, maleic and ftalic anhydrides of dicarboxilic acids that contains at least 2 to 8 carbon atoms; esters of mono, di, tri and polycarboxilic acids; EDTA; boric acid and sodium and calcium tripolyphosphates As solvents to stabilize the system it is used one or a mixture of the following compounds: water, branched or non-branched aliphatic alcohol, glycols and polyols.

    摘要: The present invention refers to a carbonylated compounds preparation process from a vegetable product and resulting carbonylated compounds. The vegetable product mentioned is from renewable resources. These carbonylated compounds can be used replacing several products mainly aldehydes.The process proposed comprises the carbohydrate activation that consists on getting the carbohydrate in touch with the Lewis' acid in order to facilitate a following nucleophilic substitution process. This activation occurs at same temperature of the carbohydrate preparation process.The mixture nucleophile/carbohydrate at controlled conditions will generate substituted carbonylated compounds. This process is carried on temperatures not lower than 20° C. and not higher than 105° C., for running time not lower than 10 minutes.It is necessary to stabilize the resulting substituted aldehyde mixture with any suitable stabilizing agent for this purpose. Stabilizing agent proportion will vary from 0 to 5% in mass. A biocide is added in order to eliminate the possibility of bacterial degradation of any remaining non-reacted carbohydrates residual. This biocide is added in proportions that vary from 0 to 1% in mass.
