羟基丙酮

METHODS 3-hydroxyestrogen reacted with dimethylsulfate in acetone in the presence of potassium carbonate.

方法以含3－酚羟基的雌激素类化合物为原料，丙酮为溶剂，在碳酸钾存在下与硫酸二甲醋反应。

Results showed that the hybrid monomer could photopolymerize effectively and both free radical and cationic polymerization processes were improved. When 2-Hydroxy-2-methyl-1-phenyl-1-propanone (1173) was introduced into hybrid system containing UVI-6976, the final conversion of propenyl ether double bond and polymerization rate increased obviously. The comparison of photopolymerization kinetics between hybrid and blend system was investigated as well.

结果表明，以硫鎓盐为光引发剂时，这三种杂化单体均可以有效进行杂化光聚合反应，丙烯基醚和丙烯酸酯双键都显示出较快的反应速度和较高的最终转化率，同时在简单结构的硫鎓盐（UVI-6976）引发体系中加入自由基引发剂2-羟基-2-甲基-1-苯基-1-丙酮（1173）后，丙烯基醚双键的阳离子聚合速率和最终转化率都有了很大提高。

Any of three compounds (acetoacetic acid, acetone, and/or beta-hydroxybutyric acid) found in excess in blood and urine of persons with metabolic disorders.

三种化合物中任意一种（乙酰乙酸、丙酮和/或β羟基丁酸），人体的血液和尿中大量含有。

The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups, belonging to chromophoric groups, during inducing discoloration under the pretreatment conditions, which makes the wood color deeper. There were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain. The interaction between the auxochromic groups and the chromophoric groups made the wood color deeper.

结论］羟基、羧基等助色基团在预处理条件下氧化成羰基、酯基等发色基团，使木材的颜色加深；刺槐木材丙酮抽出物的主要成分中含有大量发色基团和助色基团，这些基团间的相互作用使木材颜色加深。

Using the chemical reaction route selection method proposed by the authors, a reaction route of using commercial methylglyoxal as the starting material to produce Furaneol was chosen.

今采用作者提出的化学反应路径选择因子对呋喃酮的合成方法进行计算比较，确定了以丙酮醛为原料，通过偶联反应合成中间体苏式3，4-二羟基-2，5-己二酮，再由成环反应制备产物呋喃酮的合成路线。

It is found that the solubility of dl-p-HPGS is very small in pure acetone and in the solvent with low water content.

在纯丙酮和低含水量的混合溶剂中，对羟基苯甘氨酸硫酸盐溶解度很低。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
