Ⅰ Cu-3(btc)是什麼物質
BTC是(三氯甲基)碳酸酯的簡稱,是一個化學物質的簡稱,主要有碳、氯、氧組成,化學式是C3Cl6O3,可作為劇毒光氣和雙光氣在合成中的替代產物。
BTC=Bis(trichloromethyl)carbonate 雙(三氯甲基)碳酸酯,即三光氣。
CAS Registry Number32315-10-9
分子式 C3Cl6O3
分子量 296.748
(1)cu2btc3擴展閱讀:
三光氣在有機合成中用作試劑,並且是用於各種化學轉化的光氣的較不危險的替代物,包括將一個羰基鍵合至兩個醇,並將胺基轉化為異氰酸酯。
三光氣的毒性與光氣相同,因為它在加熱和與親核試劑反應時分解成光氣。 即使微量水分也會導致光氣的形成。 因此,如果對光氣採取所有預防措施,則該試劑可以安全地處理。
作為劇毒光氣和雙光氣在合成中的替代產物,本品毒性低,使用安全方便,而且反應條件溫和,選擇性好,收率高。
本品為二級有機有毒品。宜存於乾燥、陰涼、通風的庫房內,遠離火源,並與有機胺、鹼性化學品等分開保存。

可以看到Sales Code後面的白框里會有3個字母。這個就是銷售國的代碼。記下到下表中查對應的國家即可。
比如說我的9000 ,Sales Code是XEU ,在下表中可以查到XEU = UNITED KINGDOM,即代表手機是銷往英國的,歐版。TGY 就是港版

Ⅶ 我想了解一些現在流行的英語縮寫希望朋友們提供
呵呵,我這兒都是聊天用的縮寫,不知道合不合你意,不過我想,都是為了學英語嘛,應該也用得上呵呵
下面這些是一個美國朋友幫我總結的,很多都不常用,但是卻很全!有許多都是地道的美國口語,我們平常不這么說,可是正綜的老外都這么說的呵呵。另外,向你推薦一個工具,叫skype,是一個聊天工具,和QQ一樣地聊天工具,不過它的普及率遠高於QQ,全世界每個國家都有skype友,我最近正和幾個美國朋友聊得歡,一個是麻省理工學院的學生,還有一個是加州一個不出名的大學的教授,還有夏威夷的朋友。這兩天,我認識了兩個美國高中生,還有一個伊拉克人,我們四個總是一起語音聊,大家都很冷靜,美國人和伊拉克人竟然也能忘記一些東西,只談生活中的趣事。要是你對這個工具感興趣,可以到TOM網站上下載!

ps:以上信息是以上海港作為參考,來自中國國際貨運網.這里所羅列的航線,只是說比較成熟的航線,可供你參考.但是並非是絕對的,比如非洲線的話除了地中海航運外,還可以走法國達貿.澳線的話,中遠的不錯,船期准,速度快.美線的也可以APL.中東線的話象PIL,現代商船也是不錯的.還有近洋線的話,那選擇就更多了,如錦江,海華,煙台海運等等.船公司的選擇主要還是看你客人有什麼需要,是否指定船公司,還有就是價格,船期,掛靠港,目的港代理等因素了.
