브레이킹배드 season1 episode 1

1화 red phosporus 적린

yellow phosporus 황린

white phosporus 백린

황린은 공기중에서 자연발화하기때문에

물 속에 넣어서 보관하는 반면 적린은 황린과 달리 공기중에서 자연발화하지 않는다.

Phosphorus does indeed react with water vapour to produce phosphine (PH₃, IUPAC name: phosphane) [3]. It is a colourless, flammable and toxic gas (b.p. -87 °C, dangerous level ca. 50 ppm in air). However the standard industrial reaction requires white phosphorus and concentrated sodium hydroxide: 

P₄ + 3NaOH + 3H₂O → 3NaH₂PO₂ + PH₃ 

White phosphorus is much more reactive than red phosphorus. In the past red phosphorus was actually made from white phosphorus and the red product was often treated with hot water and steam to help purify it! Heated red phosphorus can react with hydrogen to make PH₃ but Walter only has steam. Phosphine gas is reported to be a dangerous by-product in the illicit production of 'meth' [2] so this may be where the idea came from in the programme. As its definitely red phosphorus that Walter is using the chemistry is not looking too good. He did heat the pan over a camping gas stove and so the sparks could have been some of the phosphorus burning in the flame (red P burns above 260 °C in air) but simply adding red phosphorus to a frying pan of steaming boiling water would not produce the clouds of phosphine gas we see in the programme.

적린, 황린과 포스핀가스는 위험물산업기사에서도 자주 다루는 부분이기때문에 낯설지 않았다. 포스핀가스가 독성물질이라는 것도 사전에 알고 있었다. 적린이 나오길래 뭔가 이상한 것 같기는 했다. 그래서 찾아보니 아니나 다를까. 이미 많이 언급되었던 브레이킹 배드의 과학적 오류였다. meth는 methamphetamine, 필로폰의 제조과정에서 포스핀가스가 부산물로 발생된다.그렇기때문에 월터가 방독면을 쓰고 있다. 아무튼 포스핀가스는 심각한 독성물질이다.
