An adipic acid esterification experiment suitable for graduate students has been developed to describe the industrial manufacture of plasticizers. Students first follow progress reaction with simple acid/base titration enabling measurement number. During workup mixture, they learn how manage filtration a viscous mixture over an inert support such as Celite and practice on atmospheric vacuum dis...

In situ product recovery (ISPR), in the form of an extractive fermentation process, can increase productivity and titers sustainable production platform chemicals. To establish a guideline for development industrially relevant processes such bio-based compounds, wide screening was performed, mapping potential extensive range solvents solvent mixtures. Besides biocompatibility with Saccharomyces...

Studies of the nutrition of certain lysine requiring mold mutants indicate that L-a-aminoadipic acid (AAA) or a-ketoadipic acid (KAA) are precursors of lysine. For example, Mitchell and Houlahan (1948) found that certain lysine requiring mutants of Neurospora crassa would respond to either lysine or AAA, and Windsor (1951) subsequently demonstrated that f-C'4-a-aminoadipic acid was completely i...

Muconic acid has gained interest as a bio-based platform chemical to produce value-added compounds including adipic and terephthalic acid. In this study, fermentation strategy based on in situ product recovery was established boost process performance counteract inhibition. An optimized reactive extraction mixture for muconic developed consisting of 12.5% (v/v) CYTOP 503 canola oil showing high...

In this work, four hydrocinnamic acid derivatives including N, N’ -succinic bis(hydrocinnamic acid) dihydrazide (HASUD), -adipic (HAADD), -sebacic (HASED) and -dodecanedioic (HADOD) were synthesized via two liquid reactions. And then fourier transform infrared spectrometer 1 H nuclear magnetic resonance used to characterize molecular structures of derivatives. Additionally, the orthogonal exper...

The biobased production of adipic acid, a precursor in the production of nylon, is of great interest in order to replace the current petrochemical production route. Glucose-rich lignocellulosic raw materials have high potential to replace the petrochemical raw material. A number of metabolic pathways have been proposed for the microbial conversion of glucose to adipic acid, but achieved yields ...

The interconversion of atmospheric organic particles among solid, semisolid, and liquid phases is of keen current scientific interest, especially for particles of secondary organic material (SOM). Herein, the influence of phase on ammonia uptake and subsequent particle-phase reactions was investigated for aerosol particles of adipic acid and α-pinene ozonolysis SOM. The nitrogen content of the ...

The asymmetric unit of the title compound, 2C(10)H(11)N(5)O·C(6)H(10)O(4), consists of a 2,4-diamino-6-(4-meth-oxy-phen-yl)-1,3,5-triazine mol-ecule and one-half mol-ecule of adipic acid which lies about an inversion center. The triazine ring makes a dihedral angle of 12.89 (4)° with the adjacent benzene ring. In the crystal, the components are linked by N-H⋯O and O-H⋯N hydrogen bonds, thus gen...
