Reinvestigation of the Two-Step Synthesis of Sevoflurane
Improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (Sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. This process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by a halogen-exchange fluorination. This is the first synthesis of Sev...

متن کاملThe environmental two-step.
An important stage in macromolecular crystallography is that of phase extension and refinement when initial phase estimates are available from isomorphous replacement or anomalous scattering or other methods. For this purpose, an alternative method called the twin variables (TwiV) method has been proposed. The algorithm is based on alternately transferring the phase information between the twin...
متن کاملThe Problems of Jurisdiction on the Internet
The relationship between jurisdiction and the internet has been the subject of wide ranging discussion ever since the boom in domestic internet usage. Without clear legislation, laws have been created on an ad hoc basis, often in response to specific cases. It is difficult to predict whether any one law will ever be sufficient to cope with the great variety of alleged crimes which take place on...
