Summary
China
Area of Science:
- Environmental Science
- Atmospheric Chemistry
- Industrial Ecology
Background:
- Nitrous oxide (N2O) emissions contribute to climate change and ozone depletion.
- China's chemical industry is a significant source of industrial N2O.
Purpose of the Study:
- To estimate historical and future N2O emissions from China's chemical industry.
- To explore the mitigation potential for N2O emissions in this sector.
Main Methods:
- Analysis of historical N2O emission data (1990-2012).
- Projection of future N2O emissions (2012-2020) under current policies.
- Quantification of mitigation potential, focusing on adipic acid production.
Main Results:
- Industrial N2O emissions in China increased 37-fold from 1990-2012 (5.07 to 174 Gg).
- Projected emissions to reach 561 Gg by 2020 without mitigation.
- Mitigation potential of 1.54 Tg for 2012-2020, primarily from adipic acid production (96.2%).
Conclusions:
- Adipic acid production is the dominant source of N2O emissions and mitigation potential.
- Significant N2O mitigation is achievable but requires effective policies and regulations.
- Addressing N2O emissions is crucial for climate change mitigation and ozone layer protection.

Microbes and Climate Change
91
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

Preparation of Amines: Reduction of Oximes and Nitro Compounds
3.7K
Oximes can be reduced to primary amines using catalytic hydrogenation, hydride reduction, or sodium metal reduction. The reduction of aliphatic and aromatic nitro compounds to primary amines takes place by either catalytic hydrogenation or by using active metals like Fe, Zn, and Sn in the presence of an acid.
Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...

Phase I Reactions: Reductive Reactions
801
Phase I biotransformation reductive reactions are chemical processes that modify drugs by introducing or revealing polar functional groups via reduction. Enzymes called reductases catalyze these reactions, playing a pivotal role in drug metabolism by transforming lipophilic drugs into more polar, water-soluble metabolites for easy excretion. An essential type of reductive reaction is the carbonyl group reduction, where aldehydes and ketones are reduced to alcohols. An example is the...

Inhalational Anesthetics: Overview
1.7K
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Preparation of Amines: Reduction of Amides and Nitriles
2.3K
Nitriles can be reduced to primary amines using reducing agents like lithium aluminum hydride or catalytic hydrogenation. The reduction introduces an amino group with an extra carbon in the skeleton. Nitriles are formed from the reaction between alkyl halides and sodium cyanide through the SN2 mechanism. Primary alkyl halides are the preferred substrates to prepare nitriles.
Amides can be reduced to primary, secondary, and tertiary amines using catalytic hydrogenation, active metals like Fe,...

The Nitrogen Cycle
46.5K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...
