[化學JJ請入] 3M 甲醛淨化除味噴霧

裝修完, 好多人都搵專業公司去清甲醛, 收你幾千到一萬...
又光觸媒
又無光觸媒
又天然素材空氣觸媒


路過見到呢隻3M™ 甲醛淨化除味噴霧

成份係benzyl-c12-16-alkyldimethyl chlorides
實際上清唔清到甲醛(formaldehyde)呢?

自推1

自推2

自推3

都係好主意

一種Quaternary ammonium compounds， 中文應該叫季銨鹽，作為表面活性劑，呢類野通常拎嚟做消毒殺菌。
除甲醛方面，未有聽聞有此能力，要再搵搵文獻先。

呢隻通常用係車入面多，不過呢種成分可以除甲醛就真係第一次聽

dse chem 表示,不如試下用1比49漂白水抹

甲醛好容易被漂白水氧化成甲酸 (蚊咬痕之化學物質) 再會係幾分鐘內變成水和二氧化碳

CLOROX disinfecting wipes 嘅主要成份

多謝呀巴打....岩岩搵到呢個

佢入邊寫 Avoid products that list these ingredients 有benzyl-c12-16-alkyldimethyl chlorides....

咁係咪根本唔適合接觸?

真唔真呀? 我文科仔真係唔識

我自己搵過呢隻成份都唔見有人講...3M話
3M™ Formaldehyde Removal Spray make use of group reaction to rapidly capture and reduce formaldehyde and pungent odors in the air.

what is group reaction ah, chem jj?

可能佢想講呢種成份有個functional group 可以同Formaldehyde 的 formyl group有reaction掛

申利: 唔識，9估

如果係真你都要狂抹，因為甲醛會不停走出來。
除非你用光觸煤封住佢之如，再利用光觸媒特性分解甲醛。

如果表面甲醛量真係多，漂白水(oxidizing agent)同甲醛(reducing agent)會有redox reaction,
CH2O --> HCOOH (甲醛-->甲酸)
OCl- --> Cl2 (漂白水-->氯氣)

氯氣係毒，但當然要睇有幾多甲醛做reaction啦，愈多甲醛就愈易還原漂白水做氯氣。

唔知有無用呀

甲醛冇咗但變咗直出毒氣

好似仲大獲...

chlorine會唔會跟住再氧化啲甲醛/甲酸
變咗無咁毒/無害嘅chlorine/chloride化合物?

睇巴打個名就知你係化學jj

benzyl-c12-16-alkyldimethyl chlorides 有嘅functional groups:
1. benzyl group (benzene ring + methylene)
2. quantaray ammonium cation group (a group with positive charge)
3. 2 Alkyl groups (just long carbon chains, one of which is 12C long and another is 16C long)

唔知邊個同aldehyde group 有 reaction
