Petroleum Radiation Processing

Book Description
Radiation-thermal cracking of oil feedstock has the potential to offer a solution to many of the challenges the oil industry is facing. Radiation-induced chain cracking reactions in hydrocarbons at lowered temperatures initiated the development of improved technological approaches, combining the advantages of radiation-thermal cracking and low-temperature feedstock processing. However, researchers still face obstacles in the practical application of theory and experimental data, and the literature presents contradictions that need to be sorted out for further development of this technology. Petroleum Radiation Processing fills an information gap, providing systematic descriptions of the fundamentals of radiation-induced cracking reactions in hydrocarbons. It analyzes the basic experiments that have brought about the rapid development of radiation technology for petroleum radiation processing during the last decades. The book provides a detailed introduction to radiation methods based on radiation-thermal and low-temperature cracking of hydrocarbons, emphasizing high-viscous oil feedstocks that are difficult to process by conventional methods—such as heavy and high-paraffinic crude oil, fuel oil, and bitumen. It helps readers understand the mechanisms and kinetics of low-temperature radiation cracking. The book addresses the application of promising radiation methods for solving critical environmental issues, such as oil desulfurization and regeneration of used lubricants and other used oil products. Examining experimental data as well as theoretical and technical approaches, it summarizes research progress in the field of petroleum radiation processing, providing a useful reference on the theory and technology of hydrocarbon radiation processing for chemical technologists, researchers, and students.

Book Description
Controlled drug release plays an important role in medicine because it can be a factor in human health care. It is defined as the ability to release a drug inside the body at a specific time. Radiation-sensitive functionalized materials can be controlled by outside triggers such as radiation and have great potential for application in controlled and targeted drug delivery. Radiation-sensitive functional groups are known and studied, however, there are very few examples. Previous studies have revealed that 2-oxoalkyl group can successfully undergo radiolytic cleavage, but under relatively high doses of radiation. It is desirable that the radiolysis efficiency of 2-oxoalkyl group be improved in order to gain applications in clinical medicine. Thus, one objective of this thesis was to study the effect of a few substituents on the radiolysis efficiency of substituted 2-oxoalkyl groups. Therefore, a few molecular probes that contain an aryl 2-oxoalkyl group with substituted acetophenone of monoesters of adipic acid, and coumarin scaffold of monoesters of adipic acid have been successfully synthesized. These compounds were studied under X-ray radiation at various doses to assess the potential of selective cleavage of the aryl oxo-methyl ester linkage. The radiolysis studies showed that less than 10% of the ester linkages in these compounds were degraded under a dose of up to 20 Gy of radiation. Compounds were also studied for their hydrolytic rate for the aryl oxomethyl ester linkage using TLC method. Hydrolysis at around neutral pH happened at a slower rate for compounds that are sterically more hindered at the oxo-methyl position. Poly-L-glutamic acid (PGA) is a natural polypeptide that is biodegradable and biocompatible. Therefore, it has been exploited as drug carrier system. In this thesis, PGA has been modified with a phenacyl group. The lipophilic phenacyl group is assumed to assist the formation of nanoparticles for the modified PGA. Radiolysis studies of such modified PGA showed that the grafted phenacyl group can be selectively cleaved upon radiation with a clinically relevant dose. Lawsone is a commercially available natural product. It has been used as starting material for the synthesis of different biologically active compounds. Lawsone also has various biological effects including anticancer activity. One anticancer mechanism of lawsone is associated with its ability to undergo one-electron reduction. Thus, another aspect of this thesis was to synthesize lawsone derivatives as potential anticancer agents. The preparation of glycosylated lawsone derivatives was of particularly interest. Direct glycosylation of lawsone using a number of methods was unsuccessful in providing fully deprotected lawsone glycosides. Then the Mannich reaction was employed to produce a group of lawsone derivatives including one compound bearing a glucose residue. The synthesized lawsone derivatives will be evaluated for anticancer activity in the future work.
