Title: The Innovations of Rodolfo W. Laurel
Introduction
Rodolfo W. Laurel is an accomplished inventor based in Corpus Christi, TX (US). He has made significant contributions to the field of chemical engineering, particularly in the production of trimethylolpropane (TMP). With a total of 2 patents to his name, Laurel's work focuses on improving the quality and efficiency of chemical processes.
Latest Patents
Laurel's latest patents include a process improvement to produce low color trimethylolpropane. This invention discloses a method for acquiring crude TMP of low reacted color, which is typically prepared by the condensation of n-butyraldehyde and formaldehyde in an alkali solution. The process involves concentrating the mixture and passing it through an extractor. It has been discovered that a high concentration of low color TMP can be obtained by taking a slip stream of hot organic/water/TMP from the extractor and allowing the mixture to cool and phase separate. Upon separation, TMP with an acid wash color of about or less than 5 GU is recovered from the water phase. The patent also discusses the use of single and multistage extractors.
Another notable patent by Laurel is focused on trimethylolpropane color improvement. This invention relates to a process for enhancing the color of TMP by extracting color-causing impurities generated during its production. The improved color TMP is characterized by a reduced acid wash color and phthalic anhydride color, which are essential measurements for assessing product quality and suitability for color-sensitive end-uses.
