Theboiling pointsof alcohols are much higher than those of alkanes with similar molecular weights. For example, ethanol, with amolecular weight(MW) of 46, has a boiling point of 78 °C (173 °F), whereaspropane(MW 44) has a boiling point of −42 °C (−44 °F). Such a large ...

The heat capacity of 99.98 mole % pure chlorodifluoromethane has been determined from 16-230°K. A λ-type transition in the solid was observed at approximately 59°K. with a heat of transition of 16 ± 2 cal. The heat of fusion at the melting point, 115.73 ± 0.01°K., was found...
FIELD: chemistry.;SUBSTANCE: invention relates to a method for processing of high-boiling by-products of trimethylolpropane production process by condensation of n-butyraldehide with formaldehyde. Di-TMP with a purity of 98 wt % or higher is recovered by successive crystallisation of bottom products...
The crystallizing point of the oil obtained from such operation, or operations, will vary with the crystallizing temperature employed, as well as with the number of successive treating operations employed. High boiling aromatic oils having crystallizing points of 0° C., -20* C., -40° C., ...
The normal BP (i.e. the boiling point at 1 atm) is one of the major physical-chemistry properties used to characterize and identify a compound. Besides being an indicator for the physical state (liquid or gas) of a compound, the BP also provides an indication of its volatility. In ...
throughout the volume of the liquid (see). The boiling point is a special case of a transition temperature for a first-order transition. Table 1 gives the boiling points of a number of substances at normal external pressure—that is, at a pressure of 760 mm Hg, or 101,325 newtons/m2...
At SATP, which of the following compounds has the highest boiling point? A) phenol B) cyclohexane C) benzene D) chlorocyclohexane Why is the boiling point of propane-1,3-diol (HOCH_2CH_2CH_2OH) higher than the boiling point of propane-1,2-diol (HOCH_2CH(OH)CH_3) (215 degrees...
