Abstract

The objective of the present work is to design a process for the production of resins with enhanced characteristics for use in the graphics industry which are in the public domain or innovatory, and the product of which possesses properties appropriate for use as a pigment vehicle in off-set printing presses. Brazil is the world’s second largest producer of tar. However, the national industry does not add sufficient value to this raw material, which is exported and later imported back in the form of finished product. Currently the company also produces tar based resins with a low added value due to the use of an outdated technology. The project includes the drawing up of a bibliography involving the study of patents and papers for the selection of possible routes of synthesis for the definition of raw materials to be used in the second stage. Trials are also planned in the Analytical Center of the Chemical Institute of the University of São Paulo, USP, and reactor bench trials in USP’s Department of Chemical Engineering with a view to obtaining a first selection of process conditions, including in this operating conditions (temperature and pressure) and the proportion of reagents to be fed in with the aim of synthesizing a resin with the desired characteristics, enabling an assessment of the technical-economic viability of the synthesis. In the second phase, in addition to the development of tar based resins with enhanced properties for use in the graphics industry, the implementation of a structure for the engineering of tar based products will be emphasized.
