This company is a specialized production industrial chemicals responsibility limited company , specialized production qu suan , hydroquinone ester , camphor biology fermentation product , the existing near 200 technical personnel and the multi - taiwan advanced equipment , guarantee the high quality , the high grade production process 本公司是一家專業生產化工原料責任有限公司,專業生產曲酸、氫醌酯、樟腦生物發酵制品,現有近200名技術人員及多臺先進的設備,確保高品質、高質量的生產流程。

Through orthogonal design experiments on synthesizing p - tert - butylcstechol from hydroquinone and isobutylene by using a new catalyst prepared from cobalt naphthenate and zinc chloride , the optimum technology parameters were obtained : mole ratio was 1 : 1 . 15 for hydroquinone and isobutylene , mass ratio was 100 : 20 for hydroquinone and catalyst , and the reaction temperature was 100 5 摘要用環烷酸鈷與氯化鋅復配的新型催化劑,以鄰苯二酚、異丁烯為原料合成對叔丁基鄰苯二酚,通過正交實驗確定的較佳工藝參數為:鄰苯二酚:異丁烯(物質的量比) 1 : 1 . 15 ,鄰苯二酚:催化劑(質量比) 100 : 20 ,烷基化反應溫度100 5 。

With the aid of the hydroquinone in the solution , the sensor displayed excellent electrocatalytical response to the reduction of h2o2 compared with enzyme - polymer modified sensor , the immobilization of enzyme was simple and the sensor exhibited a better stability and reproducibility 在工作電位- 100mv條件下,能快速催化還原過氧化氫。在傳感器制作中,酶固定方法簡單易行,制得的電極可多次重復使用,具有較好的使用價值。

The yield of benzaldehyde obtained by using the modified anode containing immobilized hydroquinone was better / worse than that obtained with a pt anode without / with hydroquinone in solution , repectively 由苯二酚固定于白金之電極所得苯甲醛之產率分別白金電極無有苯二酚存在于溶液中之產率為高低。
