2012年是世界己内酰胺发展最快的一年，全年全球产能增加到543.2万吨/年，同比增加15.4%，产量实现411.3万吨，总消费量为423.5万吨，亚洲地区是拉动供需增长的主要力量。预计到2017年，全世界己内酰胺的总产能将超过900万吨/年，总消费量将达到500万吨，产业发展将以亚洲为中心。截至2013年8月底，我国己内酰胺总产能达到141.5万吨/年，但仍产不足需，自给率仅为50%左右。较大的供应缺口以及相关产业的高增长、高回报，引发国内兴建己内酰胺的高潮，预计到2017年，我国己内酰胺的总生产能力将超过400万吨/年，成为世界最重要的己内酰胺生产国家。

《中国化工报》报道，财政部12月2日在官网发布通知，对进口天然气税收优惠政策进行了调整，一方面调高了液化天然气的销售定价标准，从而降低增值税返还比例；另一方面，又新增了多个可以享受税收优惠的进口天然气项目。下发文件中，将液化天然气销售定价调整为31.45元/GJ，管道天然气销售定价调整为1.11元/立方米。这一定价较此前的规定价格调高了26%，从而可以将倒挂比例降低，进而减少进口天然气项目的进口增值税返还数额。

2012年世界正丁醇产能409万吨/年，需求量320万吨；辛醇产能380万吨/年，需求量305万吨。亚洲地区扩能及消费是世界丁辛醇产销的主要增长因素。预计2015年世界正丁醇产能将扩大到573.1万吨/年，辛醇达473.6万吨/年。2012年我国正丁醇产能增加到91万吨/年，总消费量119万吨；辛醇产能达到116.5万吨/年，消费量116万吨。我国丁辛醇长期供不足需，对外依存度较高，未来三年，国内将有大批新建拟建产能，正丁醇和辛醇产能分别达到247.1万吨/年和206.9万吨/年，年均增长率达到39.5%和21.1%，而正丁醇下游主要消费领域丙烯酸丁酯和辛醇下游增塑剂领域增速分别在14%和5%，届时国内丁辛醇将供大于求，造成短期内产能过剩、开工率降低。

Chromatography systems are used for the purification of biochemical, environmental, and other chemical entities using the principle of separation chemistry. The major entities which are regularly separated are metabolites, proteins, carbohydrates, and salts. Chromatography systems are routinely used in pharmaceutical companies and academic institutes for commercial production of biopharmaceuticals and analysis of various molecules. Owing to the increased demand for biopharmaceuticals, the chromatography systems are automated and integrated as a unit in small to large laboratories and large commercial companies. As a result, chromatography systems have become an important accessory tool for various research and commercial purposes.

Emulsifiers are substances that help in creating a smooth mix of two or more ingredients that do not easily combine and keep them from separating. The addition of emulsifiers to immiscible liquids augments compatibility of various food ingredients such as starch, proteins, fats, and water. Food emulsifier (apart from emulsification) exhibits multiple functions such as dispersion, infiltration, foaming, de-foaming, mold release, bacteriostatics, and mutual actions between starch and protein. Food emulsifiers are widely used across the globe as they help improve the texture, product consistency, enhance the flavor, and aid in blending the ingredients of food products. Emulsifiers are widely used in the bakery industry as they improve crust thickness and provide strength to the dough. Also, emulsifiers are used by major F&B manufacturers as food additives for reducing fat content in food.
