This doc discusses pH perseverance approaches. It defines pH because the damaging logarithm of hydrogen ion focus and describes how Sorensen designed the pH scale in 1909. A pH of seven is neutral as hydrogen and hydroxide ion concentrations are equivalent.
Diazotization: respond methyl anthranilate with sodium sulfite to type two-carbomethoxy benzene-diazonium chloride. Sulfonation & oxidation: then respond with sulfur dioxide and chlorine to generate 2-carbomethoxy benzene sulfonyl chloride.
Aspartame is Just about the most studied food items additives inside the human food source. FDA scientists do not need security fears when aspartame is utilised underneath the accredited circumstances.

……我一直在研究煤焦油里的化学基团和取代物，也有了不少科学发现，但据我所知，都没有什么商业价值。一天晚上，我做实验做得太起劲儿，很晚了才急匆匆地去吃晚饭，而且还没洗手。我坐下掰了一块面包塞进嘴里，感觉甜得难以言喻。我也没多想，以为是沾了蛋糕或者果脯。我去漱了漱口，用手巾擦嘴，可这手巾竟然比面包还甜。这下我就不理解了。我又往杯子里灌水，冲洗我嘴上被我的手指碰过的地方。那水就像糖浆一般甜。我突然想到，前前后后这所有甜味都是我引起的，于是我舔了舔大拇指尖，果然是甜过这世上所有的甜品。我立马就懂了，我从煤焦油里发现或发明了一种超越任何糖的糖类。我也不吃晚饭了，一溜烟跑回实验室，兴奋地把烧杯和蒸发皿都尝了一个遍。万幸里面没有任何腐蚀性或有毒的液体。
