愈创木酚

The effect of the molar ratio of guaiacol/methyl- nitrate ,the reaction temperature, the reaction time, the choices of nitrating agent and solvent in the synthesis of 5 -nitro-guaiacol has been studied.

本文研究了愈创木酚／硝酸甲酯的摩尔比、反应温度、反应时间，硝化剂和溶剂的选择对5——硝基愈创木酚合成的影响。

The experimental results showed that Rhus Laccase polymerized the guaiacol to various low-molecular-weight polymers, two of which were identified to be tetramer and pentamer.

结果表明：漆树酶能使愈创木酚聚合为低分子聚合物，其中2种产物经鉴定为愈创木酚的四聚体和五聚体。

Dietary guaiacol significantly (P＜0.05) decreased contents of Ca and Sr, but significantly increased Mg content in shell.

愈创木酚显著降低贝壳中Ca和Sr的含量，然而显著升高贝壳中Mg的含量（P＜0.05）。贝壳中P和Zn的含量不受愈创木酚的显著影响。

The apparent Km values with guaiacol, catechol and pyrogallol as substrates were 2.75, 12.4 and 12.8mmol/L at 25℃ and pH 7.0, respectively.

该酶在25℃和0.05mol/L磷酸缓衝液(pH7.0)条件下对愈创木酚、邻苯二酚和没食子酸的Km分别是2.75、12.4和12.8mmol/L。

According to the differences of the materials, there are many methods of synthesis for benzofuranol , such as the pyrocatechol method, the cyclohexanone method, the o-chlorophenol method, the nitrophenol method, the methoxy phenol method, and so on.

根据原料的不同，呋喃酚合成方法可分为邻苯二酚法、邻氯苯酚法、环己酮法、硝基苯酚法、愈创木酚法、邻异丙基酚法、羟基苯异酮法等，文章对前几种较常见的合成方法的原理及工艺进展进行了详细的综述，并展望了呋喃酚合成方法的发展趋势。

Amounts of 2 furaldehyde and 5 hydroxymethyl 2 furaldehyde in wood vinegar from the treated wood were increased,but amounts of carboxylic acids,phenols,pyrocatechol,guaiacols,and maltol were almost constant.

与未处理材相比，处理材木醋液中糠醛及5 羟甲基糠醛的收量增加，而羧酸类、苯酚类、邻苯二酚、愈创木酚类及麦芽酚的收量几乎不变。

Wood Vinegar is a natural material that is distilled from wood. It is compose of organic acid and hydroxybenzene , Various dosage of wood vinegars, pyrolignerous acid and guaiacol were mixed into organic manure firstly in this experiment, and then, the above said organic manure are separately added into soil. Under the analysis of the amount of the edaphon, adding 10g wood vinegar to 1kg organic manure and 30kg soil can much active the edaphon effectively in a short term and make a maximum rising extent of edaphon numbers.

木醋液是从多年生柞木中经过高温蒸馏出来的纯天然物质，其主要成分是有机酸和酚类物质，为了明确木醋液和主要成分对土壤微生物的作用，将加入不同剂量的木醋液、愈创木酚、醋酸的有机肥施入土壤，观察土壤中微生物数量的变化，结果表明：在1kg有机肥中加入10g木醋液，施入30kg土壤中，土壤微生物数量增加幅度最大，土壤微生物10天内被有效地激活；同时，当在1kg有机肥中木醋液的添加量高达50g时，对土壤微生物有一定的抑制作用。

At the same time, a continuous restraint on the edaphon, including those existing in the tested roots will happen when 50g wood vinegar are added into 1kg organic manure and 30kg soil.However, the influence of pyrolignerous acid and guaiacol were not same with wood vinegars. The reason that wood vinegars can much active the edaphon effectively, is not only the pyrolignerous acid or guaiacol reacted.

此外，通过采用木醋液中的两种主要成份醋酸与愈创木酚对比试验，表明其对土壤微生物数量的影响与木醋液不相关，木醋液能起到增加土壤微生物数量的作用，虽然有可能是其他物质在起主导作用，但更有可能的是多种物质的综合作用。

The guaiacol methods of synthesizing vanillin mainly includes: nitroso group method, Glyoxalic acid method, formaldehyde method, Reimer-Tiemann method, Trichloroacetaldehyde acetochloralb method, electrolytic oxidation method.

愈创木酚法合成香兰素的方法主要有亚硝基法、乙醛酸法、甲醛法、Reimer-Tiemann法、三氯乙醛法、电解氧化法，本文综述了愈创木酚法合成香兰素的研究进展，并对愈创木酚法合成香兰素提出了展望。
