Flexicat yellow/blue catalyst produced by CRI was the fourth dehydrogenization catalyst which was used in Daqing 60KTA styrene equipment. We have taken effective ways and means to prolong the validity-period of the catalyst, including improving in-let temperature, adjusting the radio of steam/ethylbenzen, optimizing the operation of compressor etc.

CRI公司的Flexicat yellow/blue催化剂是大庆石化苯乙烯装置应用的第四批乙苯脱氮催化剂，在延长期采取了合理提高入口温度、合理匹配稀释蒸汽的用量、加强尾气压缩机的操作等有效的操作方法，使该催化剂从装填到卸载共运行了35个月，共生产苯乙烯210913吨，使用周期增加46%，增加经济效益1.5亿元。

In the prepared process, 1,8- dihydric anthraquinone and 2,3,5,4-tetrahydroxystilbene-2- O-3 -D-glucoside were chosen as detected targets, the quality of 4 prepared method, high pressure steamed method, prepared method with beans, prepared method with ginger, prepared method with yellow wine, was compared.

以1，8-二羟基蒽醌和二苯乙烯甙作为检测指标，对黑豆炮制法、姜制法、酒制法和高压清蒸法四种方法进行比较，发现高压清蒸法得到的产品中游离态蒽醌和二苯乙烯甙含量最高，分别是其它三种炮制品的1.78～1.84倍和1.06～1.61倍。

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.
