LExEN: SGER: High-Pressure, Hydrothermal Organic Synthesis: Implementation of the Hydrothermal Diamond Anvil Cell

由于压力在理解极端环境中生命的可能起源和持续生存方面的重要性，我们提出了这项高压、热液有机化学研究。拟议研究的主要目标是改进现场水热实验技术，并建立关于地下水热环境中有机合成反应的知识基础--这是极端环境中生命研究中公认的需要和机会(Holm等人，1992年明确说明，国家研究委员会，1990年含蓄地说明)。为此，我们建议开发和应用光谱方法来监测水热有机反应的速率和路径，作为相关变量的函数，包括压力、温度、pH和氢气电池，这种类型已经在地球物理实验室设计、建造和测试。该项目专注于对高压水热有机反应的现场监测。这项工作涉及水热压力池、拉曼光谱和光学显微镜的应用，以实时评估有机反应的路径和速率。我们建议在这个项目中重点完成三项任务：(1)水热金刚石池的设计和建造；(2)研究水热有机反应的现场监测技术的开发；以及(3)水热反应研究。

The principal objectives of the proposed research are to refine in-situ hydrothermal experimental techniques and to establish a foundation of knowledge regarding organic synthesis reactions in subsurface hydrothermal environments - a well-recognized need and opportunity in the study of life in extreme environments (stated explicitly in Holm et al., 1992, and implicitly in National Research Council, 1990). Toward this end, we propose to develop and apply spectroscopic methods to monitor the rates and pathways of hydrothermal organic reactions as a function of relevant variables, including pressure, temperature, pH, and H2 cells, of a type that has been designed, built, and tested at the Geophysical Laboratory.The project focuses on in-situ monitoring of high-pressure, hydrothermal organic reactions. This work involves the application of hydrothermal pressure cells, Raman spectroscopy, and optical microscopy to assess pathways and rates of organic reactions in real time. We propose to focus on three tasks during this project: (1) design and construction of hydrothermal diamond cells; (2) development of in situ monitoring techniques to study hydrothermal organic reactions; and (3) hydrothermal reaction studies.
