Molecular Weight by Boiling Point Elevation
This experiment demonstrates the use of colligative properties. The goal is to measure the molecular weight of a non-volatile solute by determining the concentration dependence of the boiling point elevation of a solution. The solvent used must be one of the compounds commonly referred to as volatile; that is, it must have an appreciable vapor pressure. One of the several useful aspects of coll...
متن کاملPrediction of boiling point and water solubility of crude oil hydrocarbons using sub-structural molecular fragments method
The quantitative structure–property relationship (QSPR) method is used to develop the correlation between structures of crude oil hydrocarbons (80 compounds) and their boiling point and water solubility. Sub-structural molecular fragments (SMF) calculated from structure alone were used to represent molecular structures. A subset of the calculated fragments selected using stepwise regression (fo...
متن کاملFrench researchers at boiling point
Over 30,000 French scientists have signed an online petition to " save research " set up last month, with a pledge to stop their administrative duties unless the government starts listening to their complaints about funding. There is one signature for every minute that has passed since the petition — aiming to save the French public research base from the latest cuts imposed by the government —...
متن کاملIterative Force-Field Calculation and Molecular Dynamics of Cyclooctanone
Body's iterative force-field computer program has been used to calculate strain energies in cyclooctanone (I). 348 MHZ 1H NMR spectra of (I) have been investigated over the temperature range of 25° to -160°C. Two conformation processes affect the 1H NMR spectrum of (I). Iterative force-field calculations on the conformations and conformational interconversion paths of ...
