  atmospheric aerosols, organic compounds coexist with inorganic salts but, until recently, were not thought to interact chemically. We have recently shown that inorganic ammonium ions, NH4+, act as catalysts for acetal formation from glyoxal, a common atmospheric gas. In this work, we report that inorganic ammonium ions, NH4+, and carbonate ions, CO32−, are also efficient catalysts for the aldol condensation

  在诸如大气气溶胶的自然环境中，有机化合物与无机盐共存，但直到最近，人们才认为它们是化学相互作用的。我们最近发现，无机铵离子NH 4 +可以作为由乙醛生成乙缩醛的催化剂乙二醛，一种常见的大气气体。在这项工作中，我们报告了无机铵离子NH 4 +和碳酸盐离子CO 3 2-也是羰基化合物醛醇缩合的有效催化剂。在NH 4 +的情况下，这是以前未知的，并且在本文之前已申请了专利。这项工作提出的动力学结果表明，对于铵盐 和对流层气溶胶中存在的碳酸根离子， 乙醛 和 丙酮 可能和集中时一样快 硫酸 并可能与他们的反应竞争 哦部首。这些催化过程可能在气溶胶中产生大量的多共轭，吸光化合物，从而影响其对气候的直接强迫。对于具有较大亨利定律系数的有机气体，这些反应也可能导致大量吸收并形成二次有机气溶胶（SOA）。这项工作加强了最近的发现，即无机盐对气溶胶中的有机化合物不是惰性的，特别是表明了常见的盐，例如铵盐 碳
• Catalytic Reactions of Homo- and Cross-Condensation of Ethanal and Propanal

  Processes of catalytic homocondensation of propanal and its cross-condensation with ethanal and methanal in the presence of aniline and amino acids have been studied. The dependence of the conversion of the reactants and selectivity of the homo/heterocondensation process on the catalyst nature and temperature has been revealed. It has been shown that the maximum acrolein selectivity is reached in the case of using benzoyl-substituted derivatives in water, with the proportion of the products of further condensation decreasing. The selectivity for the ethanal homocondensation product 2-butenal decreases simultaneously as a result of the formation of linear and branched oligomers of successive condensation.

• The Queensland Public Sector: Recent Developments in Employment Relations
  作者：Robyn Hollander、Louise Thornthwaite

  DOI：10.1111/1467-8500.00184

  日期：2000.12

  With the incumbent Labor government embracing a recentralisation of industrial relations, public sector agencies in Queensland are experiencing a dramatic shift in the framework of employment relations. This paper discusses the approach of the previous Coalition government to managing the public sector workforce and the emerging approach of the Labor government. The comparison of contrasting governmental approaches to public sector employment relations throughout the 1990s suggests that successive governments have balanced very differently the three main pressures they have faced: political, managerialist and industrial relations.
