  • Processes for obtaining a polyol from palm oil, polyols obtained from the processes, products derived from such polyol and their method of preparation
    Patent number: 10246547
    Abstract: The present invention relates to the process for production of a polyol from palm oil and of rigid polyurethane foams prepared from said polyol derived from palm oil. On the one hand, this invention provides a method for obtaining monomeric polyols from palm oil that have hydroxyl number between 50 450 mgKOH/g sample. The polyols of the present application may be obtained by means of a procedure based on the following four mother routes: Route 1: maleinisation of the fatty acids of palm oil; Route 2: glycerolysis of palm oil; Route 3: trancesterification of palm oil; and Route 4: epoxidation of unsaturated carbon-carbon links of palm oil. Additionally, other modalities of the invention permit obtaining polyols from the combination of these mother routes. In other realizations of the invention polyurethanes are prepared from polyols obtained through any of the four routes or by combinations of the same.
