Ammonia Sampling

Overcoming the Ammonia Challenge: Sampling, the Easy Way

Many processes require ammonia — but handling this volatile substance, which is aggressive in combination with water, is not easy. In particular, the need to take regular samples poses challenges for operators. Optimized processes enable faster sampling of ammonia and thus contribute to higher accuracy, lower costs and greater employee safety.

Unlocking Complex Sulfur Molecules

A Novel Approach for Synthesis of Functionalized Benzenethiol Equivalents

Organosulfur skeletons are crucial in many fields, including pharmaceuticals and electronics. Synthesizing organosulfur skeletons requires o-bromobenzenethiols. However, conventional methods face challenges due to quick oxidation and formation of highly reactive intermediates. In a new study, researchers from Japan developed a new method for synthesizing o-bromobenzenethiols from aryne intermediates via bromothiolation. This method can pave the way for the synthesis of new organosulfur compounds with applications in diverse fields.
