氢氧化钠

Commonly used hygienically cleaner to 1 per cent of the sodium hydroxide solution supported by a variety of additives, they may be dissolved and upholstery from bottles, metal salts of aluminium, copper, zinc and other metal objects, pinhole camera should be able to guarantee of caustic soda solution within minutes into rapid infiltration of labels with a bottle of avulsing and dissolved in a few minutes.

常用洗瓶清洗剂为1％氢氧化钠溶液辅以各种添加剂，完全可溶解来自玻瓶装潢的铝、金属盐、铜、锌等金属物，针孔应能保证碱液在数分钟内快速渗入标签里层使之与瓶剥离，并在数分钟内溶化。

This reaction was performed identically to the elimination except that the 60% hydroxide solution was replaced with 5% sodium hypochlorite.

这种反应是相同的表现消除，但60 ％的氢氧化钠溶液代替用5 ％次氯酸钠。

The results indicated that the extraction ratio and properties of oil from silver carp, such as iodic value, acid value, peroxide value and soapstock content are significantly affected by extraction conditions.

结果表明，提取条件对鱼油的提取率、碘价、酸价、过氧化值和含皂量具有重要影响，适宜的制备工艺为脂肪糜于pH9.0的氢氧化钠溶液(1：1，W/V)中45℃水解5min，然后于1.0%氯化钠溶液中80℃盐析5min。

Economics evaluation:materials(urine glass,test tube,sipper,columnella, kieselguhr),reagent,consumption of instrument(pH meter, GC/MS,carrier gas,heating element,injector,sample injector),service charge, 80.00 yuan totally. Conclusion Compare with the other biology materials,as a study target,urine is easy to get and preserve,otherwise,it also contains several biology information.

共需3小时。经济学评价：取检材材料费(尿杯、试管、吸管、小柱)、检测试剂衍生化试剂、内标、浓盐酸、氢氧化钠、固相萃取材料(硅藻土的费用和仪器的消耗费(pH计、GC/MS、载气、加热器、注射器、微量加样器)，共计八十元左右。

NH4+ when heated with sodium hydroxide solution, a colorless gas is given out which can turn wet red litmus paper to blue.

With the material of magnesium chloride and sodium hydroxide,Magnesium hygdroxide was produced by adding Magnesium hygdroxide seeds .

以氯化镁为原料，以氢氧化钠为沉淀剂，采用加入氢氧化镁晶种的方法制备氢氧化镁。

However, it is to be noted that activity of sodium hydroxide with respect to the ester exchange reaction is not sufficient, and in order to improve the conversion rate of the waste edible oil to 90%, it is necessary to add methyl alcohol (stoichiometrically required amount of methyl alcohol is about 3 mole with respect to 1 mole of vegetable oil) and catalyst excessively.

不过，这是必须指出的活动氢氧化钠与尊重向酯交换反应是不足够的，并且为了提高转换率的废油脂至90 ％，这是必要的添加甲醇（ stoichiometrically要求金额甲醇约3摩尔与尊重，以1摩尔植物油）和催化剂过分。

The mignonette element's lye microwave extraction process related influencing factor carries on the single factor analysis and the orthogonal experiment to the peanut shell in discusses.The experimental result indicated:The fluid material the influence is bigger than to the extraction rate,Next is the microwave extraction time,Is small what to the extraction rate influence is the sodium hydroxide density.

对花生壳中木犀草素的碱液微波提取工艺有关影响因素进行单因素分析和正交实验探讨，实验结果表明：液料比对提取率的影响最大，其次是微波提取的时间，对提取率影响较小的是氢氧化钠的浓度。

Add-on enters certain volume the peanut shell smashing the caustic soda solution, withdraws the mignonette element using the microwave method from the peanut shell.
