Formation of 2-chloro-2-methylbutane from 2-methyl-2-butanol:

Of the other compound, we had 10 mL 1-butanol, or 8.095 g, because it has a density of 0.8653 g/mL. Therefore, we have .10921 moles of this, because its molar mass is 74.121.

Butanol is moderately soluble because of the balance between the two opposing solubility trends.

Xiaoxi Huang was born in China. He received a B.S. degree in pharmaceutical science (2011) from the Peking University Health Science Center. He is now a Ph.D candidate in the Department of Chemistry and Chemical Biology, Rutgers University, under the supervision of Prof. Tewodros (Teddy) Asefa. His current research interests include the design and synthesis of novel multifunctional nanomaterials for biomedical and catalysis applications.

Tewodros (Teddy) Asefa is currently a professor in the Department of Chemistry and Chemical Biology and the Department of Chemical and Biochemical Engineering at Rutgers University in New Brunswick, NJ. He is also a member of the Rutgers Institute for Materials, Devices, and Nanotechnology (IAMDN) and the Rutgers Energy Institute (REI). In December 2009, he helped to put together the Rutgers Catalysis Research Center (RCRC). His group at Rutgers is involved in the development of synthetic methods of a wide array of functional and core/shell nanomaterials and the investigation of their potential applications in catalysis, electrocatalysis, targeted delivery of drugs to specific cells, nanocytotoxicity, solar cells, and environmental remediation. He is a recipient of the National Science Foundation (NSF) CAREER Award (2007–2012), the NSF Special Creativity Award in 2011, the Rutgers Board of Governors Research Fellowship in 2012, and multiple federal and local research grants. He was named the National Science Foundation American Competitiveness Fellow (NSF ACIF) in 2010 and also serves as a panelist for several federal and international agencies. He has recently coedited a book on nanocatalysis (Wiley) and has written over 120 peer-reviewed scientific papers and several book chapters over the past decade.

Xiaoxin Zou was awarded a Ph.D. in inorganic chemistry from Jilin University, China, in June 2011, and then moved to the University of California, Riverside, and then Rutgers, The State University of New Jersey, as a postdoctoral scholar from July 2011 to October 2013. He is currently an associate professor in the State Key Laboratory of Inorganic Synthesis and Preparative Chemistry at Jilin University. His research interests focus on the design and synthesis of noble-metal-free, nanostructured, and/or nanoporous materials for water splitting and renewable energy applications.

François-Xavier Felpin was born in Villefranche-sur-Saône, France, in 1977. He received his Ph.D degree in 2003 from the University of Nantes under the supervision of Professor Jacques Lebreton working on the synthesis of alkaloids. After receiving his Ph.D., he was engaged in a postdoctoral position with Professor Robert S. Coleman at The Ohio State University working on the synthesis of mitomycin. In 2004, he joined the University of Bordeaux as an assistant professor and received his habilitation in 2009. In the fall of 2011, he moved to the University of Nantes, where he was promoted to full professor. Prof. Felpin is a junior member of the Institut Universitaire de France, and he recently received the 2014 Young Researcher Award from the French Chemical Society. His research interests include heterogeneous and homogeneous sustainable catalysis, new technologies, and material chemistry.

AB - Strontium phosphate hydroxyapatites (Sr-HAP) with various Sr/P molar ratios were synthesized under hydrothermal conditions. X-ray photoelectron spectroscopy revealed a close correlation between the near-surface and bulk Sr/P molar ratios of catalyst samples. Sr-HAP catalysts show high 1-butanol selectivity in the gas-phase conversion of ethanol. Sr-HAP catalysts with higher Sr/P molar ratios showed higher catalytic activity and 1-butanol selectivity. The density of both relatively strong basic sites and acidic sites was seen to increase with increasing Sr/P molar ratios, though the basic site density was significantly higher than the acidic site density. The rate-determining step in ethanol conversion over Sr-HAP catalysts was considered to be the dimerization process, as aldol condensation is mainly accelerated by base catalysis, which would explain why the Sr-HAP catalysts with higher basic site density showed higher catalytic activity and 1-butanol selectivity.

1-Butanol, 99.5% for synthesis - ITW Reagents

Mix 11.1 g NaBr + 10 mL H2O + 10 mL 1-butanol + 10 mL HCl in 100 mL RB flask; mix well while cooling in ice (must be in ice when 10 mL HCl is added), set up apparatus for reflux.

Ethanol to butanol conversion shows sustainable potential

N2 - Strontium phosphate hydroxyapatites (Sr-HAP) with various Sr/P molar ratios were synthesized under hydrothermal conditions.

Unfortunately, 1-butanol is hard to synthesise on a large scale.

Note: 1-butanol and sodium bromide are used together as reactants for the first experiment, and 2-methyl-2-butanol and hydrochloric acid are used together as reactants for the second experiment.
