21891.两种新型多孔金属-有机凝胶的合成、表征与气体吸附性能
[化学原料和化学制品制造业] [2015-06-17]
以1,4-二(3-乙酰丙酮基)苯(DAB)为有机配体分别与铝离子和铬离子反应,合成出2个新型的金属-有机凝胶:Al-湿凝胶和Cr-湿凝胶,通过直接干燥法得到相应的2种多孔干凝胶:Al-干凝胶和Cr-干凝胶.通过X射线粉末衍射仪(PXRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱仪(FTIR)、热重分析仪(TGA)、X射线能谱仪(EDS)和氮气吸附-脱附仪对凝胶材料的结构和形貌进行了表征.结果显示,2种多孔金属有机凝胶材料是由球状纳米粒子堆积而成,具有较高的比表面积、丰富的微孔及少量的介孔结构.气体吸附性能测试结果表明,Al-干凝胶的比表面积为790.3 m2/g,在1.01×105Pa,77K下能够吸附117.45 cm3/g的氢气,在273K下能够吸附60.74 cm3/g的二氧化碳.

[化学原料和化学制品制造业,汽车制造业,橡胶和塑料制品业] [2015-06-14]
High-barrier pouches are made of high-performance films and barrier resins, and have unique features such as high or low heat conductivity, resistance to external or internal conditions, special surface properties, high purity, and mechanical properties. High-performance films are thin films made from polymers such as polypropylene, polyamide, polyethylene, polyvinyl chloride, polycarbonate, ethylene vinyl alcohol, and polyester. High-barrier pouches ensure the safety of their contents and are primarily used for non-retort food products.

21894.全球高吸水性树脂SAP市场报告（2015-2019年）
[化学原料和化学制品制造业] [2015-06-14]
Superabsorbent polymers (SAPs) are chemically or physically cross-linked acrylic homo-polymer gels that are capable of absorbing liquids. The capacity of absorbency is dependent on the degree of cross-linking. SAPs are used in a wide range of applications such as baby diapers, adult incontinence products, feminine hygiene products, agriculture, mining, medical, and others.

[化学原料和化学制品制造业,医药制造业] [2015-06-14]
Teeth whitening is a bleaching process that removes stains and corrects discolored teeth using chemicals such as carbamide peroxide and hydrogen peroxide. The process has gained popularity over the past two decades, evolving from a treatment for correcting trauma-related teeth discoloration to a cosmetic treatment for enhancing personal appearance.

21896.全球汽车市场冷却液报告（2015-2019年）
[化学原料和化学制品制造业,汽车制造业] [2015-06-13]
An engine coolant is a heat transfer liquid used to remove the surplus heat from an ICE. It also helps in providing protection against corrosion and preventing freezing during winters. In terms of products, coolant is classified into three categories: ethylene glycol-based, propylene glycolbased, and glycerin/glycerol-based coolants. Ethylene glycol-based coolants are extensively used in the global automotive industry. Since they are toxic, automotive manufacturers are shifting to coolants made of propylene glycol. Owing to advances in technology and to meet automobile manufacturers’ need for coolants with longer lifespans, manufacturers are developing coolants with longer replacement cycles. The rising demand for automobiles (passenger cars and commercial vehicles, especially LCVs) in emerging countries positively affects market growth, as does an increase in the average lifespan of automobiles due to the advanced technologies used in their manufacture.

Contrast media or contrast agents are chemical substances that help enhance the internal structure of the body. They are widely used in radiology, interventional radiology, and interventional cardiology in diagnostic imaging techniques such as CT scans, MRI, X-rays, ultrasound, and other related techniques. They provide high-quality images for better diagnosis and accuracy. Contrast media can be segmented into iodinated, barium-based, and gadolinium-based contrast media.

[科学研究和技术服务业,化学原料和化学制品制造业,医药制造业] [2015-06-13]
Antimicrobial and antibiotic drugs are used to treat various conditions that affect animals such as companion animals, swine, cattle, horses, and fish. These drugs are also used to accelerate the growth of animals, especially in North America and Europe. However, an overuse of antibiotics has led to the development of antibiotic-resistant strains of microorganisms. This is a worrying trend as the resistant microbes could be transferred to humans by the consumption of milk or meat. Hence, organizations such as the CDC in the US and RUMA in the UK recommend judicious use of antibiotics in animals and strictly regulate the market.

21899.全球氯乙酸（MCAA）市场报告（2015-2019年）
[化学原料和化学制品制造业] [2015-06-12]
MCAA, also called chloroacetic acid, is a bi-functional molecule structured acid that finds extensive usage as a chemical intermediate for the production of numerous industrially and commercially important chemicals, including glycine, CMC, TGA, and cyanoacetic acid. MCAA is commercially produced by the chlorination of acetic acid in the production of acetic anhydride as a catalyst, and is sold in the form of 100% molten flake or molten solution and 80% solution in water or alcohol. Apart from its use for producing 2,4-D and methanoates for use in herbicides and the above mentioned industrial chemicals, it is also used for the production of betaine-type surfactants, synthetic caffeine, and vitamins.

Surfactants or surface active agents reduce the surface tension between two liquids or between a solid and liquid. They exhibit hydrophilic and lipophilic properties. Based on their application, surfactants are mixed with pH boosters or builders to formulate household and industrial detergents and personal care products. The important characteristics of surfactants are foaming, detergency, dispersion, penetration, and wetting effect.
