烯丙醇和環氧氯丙烷在三氟化硼乙醚絡合物的催化作用下進行加成和環化反應制得標題化合物。Taed is often used with sodium perborate and sodium percarbonate to form a good bleaching system. the main bleaching agent in this system is peracetate anion, which can increase whiteness and remove dirt, e. g., stains, tea stains, juice, and wine stains
Taed與過硼酸鈉或過碳酸鈉組合使用作為洗滌過程中的氧化物漂白系統，它們在水中反應後生成的過乙酸陰離子是該系統中的主要漂白劑，起增白、去污（如咖啡、茶、紅酒、咖哩、果汁和蔬菜等污漬）和抗微生物作用。In 2005, 61 physical and chemical parameters were measured and analysed in sediments. these included particle size, electrochemical potential as highly anoxic sediment with negative potential is related to organic pollution, chemical oxygen demand which indicates organic pollutants, total sulphide inorganic constituents, source of the unpleasant - smelling gas hydrogen sulphide, 15 metals and metalloids aluminium, arsenic, barium, boron, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, silver, vanadium and zinc, and trace toxic organics pahs and pcbs - 16 compounds and 18 congeners respectively
2005年，沉積物監測包括分析61種物理及化學參數，其中有粒子大小電化學勢有機污染促使沉積物缺氧，而讓電化學勢呈負數值化學需氧量顯示有機污染程度總硫化物無機物，是造成難聞氣體硫化氫的主因15種金屬及準金屬鋁砷鋇硼鎘鉻銅鐵鉛錳汞鎳銀釩及鋅和痕量毒性有機物多環芳烴及多氯聯苯分別為16種復合物及18種同質物。Since 1980s, taed is mainly used as bleaching activators of persalts in cleaning products. it can perform under low temperature and in less time than peroxides alone. a recent report shows that under different ph taed reacts with hydroperoxides differently
自70年代以來， taed就主要作為低溫漂白活性劑與過酸鹽（如過硼酸鈉，過碳酸鈉）組合應用於洗滌產品中，這樣就可以清除因洗滌時間、溫度致使過氧化物無法洗凈的污物。It reacts with hydrogen peroxide in the solution and forms a stronger oxidant ( peracetate anion ). since 1970s, taed has been applied to detergents and washing powder as a bleaching booster of peroxides. it can remove the dirt that is difficult to be disposed of by peroxides alone
自70年代以來， taed就主要作為低溫漂白活性劑與過酸鹽（如過硼酸鈉，過碳酸鈉）組合應用於洗滌產品中，這樣就可以清除因洗滌時間、溫度致使過氧化物無法洗凈的污物。The reaction temperature, the proportion of solid materials, the liquid - solid ratio, the reaction time making fire - retardant low hydrated zinc borate from zinc oxide, zinc nitrate and borax were discussed
摘要以氧化鋅，硝酸鋅和硼砂為原料生產阻燃劑低水合硼酸鋅，對生產工藝條件中的反應溫度，物料配比，液固比和反應時間等方面進行了研究。Unlike high - temperature superconductors ( copper oxide materials that superconduct at temperatures as high as 130 k ), mgb2 seems to be a traditional superconductor, albeit a novel variant
和高溫超導體（主要成份為銅氧化合物，轉變溫度最高可達130k ）不同的是，硼化鎂雖然是個新登場的超導材料，看起來卻很像傳統超導體。Sodium peroxoborate tetrahydrate
