Conceptual Design of n-Butyl Acetate Synthesis Process by Reactive Distillation Using Residue Curve Maps
Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and UNIQUAC models to calculate the physical properties of the system. The results showed that the unstable node branch emerged from the n-butyl ace...
متن کاملThe Chemical Nature of Residue Antigen Prepared from Yeast
Residue antigen recognizable by the precipitin test can be prepared from yeast as from bacteria. The active material appears to be identical with a complex carbohydrate, the "yeast gum" of Salkowski. In the purest form of it obtained small amounts of both nitrogen and phosphorus are still present, either as impurities or as part of the molecule. The yeast gum is not antigenic in the sense of pr...
متن کاملEffect of tillage and residue management on productivity of soybean and physico-chemical properties of soil in soybean–wheat cropping system
A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...
متن کاملSolid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
متن کاملAb Initio Quantum Chemical Studies of 15N and 13C NMR Shielding Tensors in Serine and Complexes of Serine- nH2O: Investigation on Strength of the CαH…O Hydrogen bonding in the Amino Acid Residue.
In this paper, the hydrogen bonding (HB) effects on the NMR chemical shifts of selected atoms in serineand serine-nH2O complexes (from one to ten water molecules) have been investigated with quantummechanical calculations of the 15N and 13C tensors. Interaction with water molecules causes importantchanges in geometry and electronic structure of serine.For the compound studied, the most importan...
