Abstract

Small scale gas reactors can be constructed easily by making use of PTFE membranes. The membranes are employed to separate reaction compartments, where gas-evolving reactions take place, from solutions of reagents needed for qualitative or quantitative determinations of the gases. The PTFE membranes allow free flow of gases while they prevent the passage of water. Examples are given for general experimental procedures including gas-evolving biochemical reactions and preparation of harmful gases such as Cl2 or H2S.

  Abstract:
  Although trimethylamine [(CH₃)₃N] and ammonia [H₃N] are both recognized as classic Lewis bases, their reactions with the classic Lewis acid borane [BH₃ from diborane] was very different. Trimethylamine gave the expected trimethylamine borane [(CH₃)₃NBH₃] ...
