Quantum Parameter

The velocity of sound is calculated for each of the isotopic forms of liquid hydrogen using the quantum cell model. The velocity of sound increases as the pressure increases and decreases as the temperature increases. Also the reduced velocity of sound decreases as the value of the quantum parameter, Λ*, increases. In addition, the thermodynamic properties of liquid hydrogen compressed by a shock wave are calculated.

Mild Conditions

Preparation of oxytocin, arginine-vasopressin and its deamino-analogue serves as an example of use of 2,4,6-trimethylbenzyl group for protection of the cysteine sulfur atom in the peptide synthesis. This modified benzyl group is sufficiently stable under conditions of solvolytic removal of common amino-protecting groups and it can be cleaved off under mild conditions with liquid hydrogen fluoride or trifluoromethanesulfonic acid.
