一般描述

碳酸氢钾是一种市售的无毒碱,在研究和工业应用中经常用作试剂和pH调节剂。

应用

碳酸氢钾可被用作:      
  • 由环氧丙烷、超临界二氧化碳和甲醇合成碳酸二甲酯和丙二醇的催化剂。在此过程中,KHCO3 还起到干燥剂的作用。      
  • 在二氧化硅负载的氧化钒作为催化剂存在下丙烯环氧化中的掺杂剂。      
  • 通过Ag2CO3 催化炔丙胺的羧化环化合成 Z-5-亚烷基-2-恶唑烷酮的羧基源。

High sodium chloride (NaCl) intake can induce low-grade metabolic acidosis (LGMA) and may thus influence bone and protein metabolism. We hypothesized that oral potassium bicarbonate (KHCO(3)) supplementation may compensate for NaCl-induced, LGMA-associated bone resorption and protein losses. Eight healthy male

Liquefaction of glucose into oil was examined in hot-compressed water at 300 degrees C and 30 or 60 min in a tumbling batch reactor. The effects of alkali (KHCO(3)), a hydrogenating agent (HCO(2)H), and a cobalt catalyst (Co(3)O(4)) were studied.

Bicarbonate has been implicated in bone health in older subjects on acid-producing diets in short-term studies. The objective of this study was to determine the effects of potassium bicarbonate and its components on changes in bone resorption and calcium excretion
