加碱

The extracting coenzyme Q_(10) from Blakeslea trispora using saponific ation was also studied by orthogonal test. And the optimum extracting conditions were obtained as follows: Wet culture was distilled at 70℃for 60min, added caustic potash up to 1.9 times of dry culture, pyrogallol up to 1/2 dry culture, and the concentration of alkali-methanol was 10%.The average recovery of CoQ_(10) was 81.5%.

采用正交实验，对醇碱皂化法提取三孢布拉氏霉菌体中辅酶Q_(10)的各工艺条件进行了研究，确定最佳的工艺条件为： KOH加量为干菌体质量的1.9倍，醇碱浓度为10%，焦性没食子酸添加量为干菌体质量的1/2，在70℃下皂化60min，其平均提取收率达81.5%。

Cephalotaxine ester of 2-oxo-6-methylheptanoic acid was treated with lithium diisopropylamide and Me O-(1-methoxyisopropyl)glycolate to give a mixture of homoisoharringtonine and its stereoisomers with 56% yield. The four stereoisomers separated by TLC showed identical mass spectra and almost superimposed IR but with different 1H NMR spectra. The configuration of the 2'-C and 3'-C of the four isomers were postulated based upon their 1H NMR spectra as compared with the 1H NMR spectra of isoharringtonine and its stereoisomers.

2-氧代-6-甲基庚酰基三尖杉碱(3)与0-(1-甲氧基异丙基)羟基乙酸甲酯(4)在强碱性试剂二异丙胺锂存在下，起亲核加成反应，反应中间体5在室温用酸性丙酮水解，得到一种新的三尖杉酯类生物碱一一高异三尖杉酯碱(6c)及其立体异构体(6a、6b、6d)的混合物，产率56%、通过制备薄层层析分得这四个立体异构体，它们的1H NMR和异三尖杉酯碱及其立体异构体的1H NMR类似，推定了它们的绝对构型。

81 Was prepared by the reaction of tris2-(salicylideneiminoethyl amine with zinc picrate [Zn2] in ethanol.

在不加任何碱的条件下，三[2-乙基]胺与苦味酸锌[Zn26H2O]在乙醇中反应，得到了较为少见的多胺单缩合西夫碱配体的配合物[ZnN(CH2CH2NH2)2(CH2CH2N=CH-C6H4O)]Pic。

Michael addition reaction must be carried out in the base of the catalyst, the alkali used are: sodium, sodium ethoxide, sodium hydride, sodium amide ...

迈克尔加成反应必须在碱的催化下进行，常用的碱有：金属钠、乙醇钠、氢化钠、氨基钠。。。

The alkali dosage depends mainly on the constituents and property of material and the quality requirements for pulp: more alkali dosage will speed up cooking process, reduce the hardness of pulp and improve the bleachability of pulp; but excessive alkali dosage will lower the pulp yield and physical intensity, while too less alkali dosage will result in harder and darker pulp, uneasy to bleach, too much screenings, and even extending cooking time cannot guarantee the reaction of delignification.

用碱量主要取决于原料的组成和性质及对纸浆的质量要求：加用碱量有利于加快蒸煮速度降低纸浆硬度和提高纸浆的可漂性：但过高却会降低纸浆得率和物理强度，如过低时，成浆较硬而色暗，不易漂白而且筛渣多即使延长蒸煮时间也难以保证脱木素反应进行。

The Langendorff model was used, and isolated perfusedrat hearts were separated into untreated, isoflurane, chelerythrine plus isoflurane, and chelerythrine groups.

使用 Langendorff 模型，离体灌注大鼠心脏被分为未治疗组，异氟醚组，白屈菜红碱加异氟醚组和白屈菜红碱组。

By observation under alkaline condition, it was found that the law of change for SCOD and dissoluble protein in the supernate of sludge was similar.

通过观测碱处理污泥上清液中的SCOD以及溶解性蛋白质，发现两者变化规律相似，其融胞效果随pH值的升高，即碱投加量的增加而增加。

Excellent dispersivity in water and stability, acid and basic -resistant, electrolyte -resistant, but also cold-resistant Test on the leather showed that when lubricating with this fat liquor, it makes the leather glazy, flexible, plentiful.

耐酸，碱及电解质溶液。具有很好的耐寒性。应用实验表明，用该加脂剂对皮革进行加脂，可使革身丰满，柔软，富有弹性，具有理想的丝光感。该加脂剂可明显地消除革的部位差和解决松面问题，使用量少。

METHODS:Based on the model of human umbilical vein endothelial cell, this study adopted Rose Bengal Stain, cell ELISA, immunocyto-chemical techniques to investigate the effect of berberine on PMN-endothelium adhesion and the expression of cell adhesion molecules.

以小檗碱加IL-1、TNF处理人PMN或人脐静脉内皮细胞后，用蛋白染料染色法研究小檗碱对PMN与HUVEC粘附的作用，用细胞ELISA、APAAP法研究小檗碱对细胞表面粘附分子表达的影响。

3 By dose alkali in a two-pass RO system ; the formula can be used as a reference for design and debugging of the system to calculate the added alkali in two-pass RO .

本文根据水中碳酸平衡原理分析了反渗透系统产水pH值的变化，得出pH值下降量等于系统对HCO3-透过率的负对数的结果，并导出了在两级反渗透系统中加碱调节pH值至8。
