题目:

中央电视台新闻栏目2006年5月14日报道齐齐哈尔第二制药有限公司生产的假药事件,“齐二药”违反规定,购入工业用“二甘醇”代替医用丙二醇(C3H8O2)作辅料,用于“亮菌甲素注射液”的生产,导致多名患者肾功能衰歇,造成多名患者死亡。二甘醇又称乙二醇醚,分子式为C4H10O3(HO-CH2-CH2-O-CH2-CH2-OH),二甘醇是一种重要的化工原料,可以制取酸、酯、胺等,其主要产品有吗啉及其衍生物1,4-二恶烷()等被广泛应用于石油化工、橡胶、塑料、制药等行业,用途十分广泛。二甘醇一般的合成路线为:

 

物质A

 
        过程Ⅰ           Br2             条件Ⅱ           反应Ⅲ

 

①              ②               ③               ④

请回答下列问题:

(1)下列关于“丙二醇”和“二甘醇”及“乙二醇”的有关说法正确的是

A.丙二醇是乙二醇的同系物       

B.它们具有相同种类和数目的官能团,性质上完全相同

C.“丙二醇”和“二甘醇”在病人体内都能被氧化为草酸 

D.分离“丙二醇”和“二甘醇”可采用分液的方法

(2)过程Ⅰ是石油加工中常用步骤,其名称为       。

(3)从物质B到物质C的过程如果条件控制不好会生成物质E,E可用于金属的切割,则为了能得到二甘醇D,物质B到物质C的反应条件是       ,该反应属于      (添反应类型)。写出B可能生成E的化学方程式:                                 。

(4)物质D是二甘醇,则合成路线中的物质A、B、C的结构简式分别是:

A:                B:                 C:          

(5)反应Ⅲ的化学方程式为:                                        。

(6) 写出二甘醇制备1,4-二恶烷的化学方程式:                         。

     Joanne was stuck in a traffic jam in central Birmingham at 5:30,   and at 6:30 she was expected to

be chairing a meeting of the tennis club. At last,   the traffic was moving. She swung quickly racing to

her house. As she opened the door,   she nearly tripped over Sheba.

    "Hey,   Sheba,   " she said,   "I've got no time for you now,   but I'll take you out as soon as I get

back from tennis club."Then she noticed Sheba seemed to be coughing or choking. Obviously,   she

could hardly breathe. Immediately,   Joanne realized she would have to take her to the vet(兽医).

When she got there,   the vet was just about to close for the day. Seeing the state of Sheba,   Dr.

Sterne brought her quickly into his office.

     "Listen,   doctor,   I'm really in a rush to get to a meeting-can I leave her with you,   and go and

get changed? I'll be back in ten minutes to pick her up,   and then I'll take her on to the meeting with

me. Is that OK?"

    "Sure,   " said the doctor.

     Joanne made the quick trip back to her house in a couple of minutes. As she was once more

entering the hallway,   the phone by the door began to ring.

     "This is Dr. Sterne,   "said an anxious voice. "I want you to get out of that house immediately,   "

said the doctor. "I'm coming round right away,   and the police will be there any time now. Wait

outside!"

     At that moment,   a police car screeched to a stop outside the house. Two policemen got out and

ran into the house. Joanne was by now completely confused and very frightened. Then the doctor

arrived.

     "Where's Sheba? Is she OK?"shouted Joanne.

     "She's fine,   Joanne. I took out the thing which was choking her,   and she's OK now."

     Just then,   the two policemen reappeared from the house,   halfcarrying a whitefaced man,   who

could hardly walk. There was blood all over him.

     "My God,   "said Joanne,   "How did he get there? And how did you know he was there?"

     "I think he must be a burglar."said the doctor. "I knew he was there because when I finally removed

what was stuck in Sheba's throat; it turned out to be three human fingers."
