Our society has relied mostly on fossil-based materials as source of carbon for industrially important chemicals. The non-renewability of this petroleum-based material, however, requires an alternative for sustainability. Presently, there has already been great advancement in utilizing biomass as a renewable carbon source. Triacetic acid lactone (TAL) has been explored as a potential renewable platform chemical by the Center for Biorenewable Chemicals (CBiRC). In the presence of microbial and enzymatic biocatalysts, TAL can be biosynthesized from glucose. Subsequently, TAL can be transformed to variety of high-valued commodity chemicals using chemical catalysts.
In Chapter 1 of this work, an efficient method was developed to utilize TAL in the 3-components Mannich reaction. This multi-component reaction is an efficient way of making highly-functionalized molecules. The participation of TAL as the enolizable component in the Mannich reaction has not been well studied in the literature. The successful production of Mannich bases containing TAL moiety demonstrates the versatility of TAL as a platform chemical.
In Chapter 2, the corrosion inhibition activity of 2-pyrones, pyridines, and TAL-derived Mannich bases in mild steel was evaluated. There already exist organic molecules corrosion inhibitors. Some TAL-based molecules and pyridines, however, have not been very well known for this application. This chapter gives an overview of other potential small organic molecule corrosion inhibitors. Structure similarity with the previously studied, opuntiol, is the basis for evaluating the efficiency of these molecules. Further studies are still needed to compare the activity of these organic molecules with the corrosion inhibitors used in the industry.
