Synthesis and Characterization of Allyl Terpene Maleate Monomer

Terpenes and their derivatives are sustainable, renewable chemicals that can be used as a complementary hydrocarbon. The exceptions are fossil-based feedstocks and lignin-based feedstocks. A simple method has been found to prepare allyl terpene maleate monomer by substitution reaction at lower reaction temperatures. Using terpenes from turpentine, maleic anhydride and allyl chloride as reactants, the synthesized monomer, terpene-diallyl maleate adduct, was prepared by D-A addition, hydrolysis, and substitution reaction. The resultant monomer was characterized for the first time. The synthesized product will be a versatile monomer and a very important intermediate, having broad application prospects. The synthesized monomer will replace similar aromatic compounds in certain applications because of its low-toxicity and sustainability. The synthesized monomer with two terminal olefin structures has great free radical polymerization potential, according to its physical and chemical properties and exploratory experimentation.

Exploratory experimentation and taxonomy of experimentation

Transformation of the philosophy of science during the last three decades is largely based on the philosophers? insights in the experimental side of science. Central issues in this new field, such as classification of basic elements and types of experimentation, are still developing. Subject of this work will be one of these types, Steinle?s ?exploratory experimentation? (EE), and its place in taxonomy of experimentation. After presenting an array of historical cases of experimentation, I analyze Elliott?s systematization of EE subtypes. I will claim that it does not represent development of Steinle?s ideas, although it can be used to improve taxonomy of experimentation in general. Special attention will be dedicated to the development of this taxonomy and understanding forms of experimentation not focused on theory testing - specifically EE.
