Ko te Methyl he puhui pararopi me nga ahuatanga e whai ake nei:

1. Te ahua: He wai kore tae ki te kowhai marama.

2. tātai rāpoi: C8H7BrNO2.

3. Taumaha rāpoi: 216.05g/mol.

4. Wairewa: He wairewa i roto i nga whakarewa pararopi penei i te waiwaro me te dichloromethane, karekau i te wai.

5. Ira Whakarewa: mo te 26-28 ℃.

Ko ona whakamahinga matua ko:

1. Te Whakakotahitanga Organic: Ka whakamahia te Methyl hei takawaenga whakahiato pararopi mo te whakahiatotanga o nga momo momo puhui waro.

2. Te rangahau pesticide: Kei te whakamahia ano i roto i te rangahau pesticide hei tohu waihanga mo te pesticides.

Tikanga:

Ka taea te whakarite i te Methyl L ma nga waahanga e whai ake nei:

1. Tuatahi, ka tauhohehia te waikawa 2-picolinic (Pyridine-2-carboxylic acid) ki te methylisium bromide (methyllitium) hei whakaputa i te 2-methyl-pyridine (Methyl pyridine-2-carboxylate).

2. Na, ka tauhohehia te 2-Methyl formate pyridine ki te sulfoxide brominated (Sulfuryl bromide) kia whiwhi methyll.

Mōhiohio Haumaru:

1. Ko te rokiroki o te Methyl L me kawe ki tetahi waahi pai-hau, me te karo i te ra tika.

2. I te wa e whakamahia ana, me mau nga karapu tiaki me nga karaehe, karohia te whakapiri tika ki te kiri me nga kanohi.

3. I roto i te tukanga o te raweke kia karo inhalation o tona kohu, me ki te mahi i roto i te pai-hā tikanga taiwhanga.

4. Mena ka pa mai, ka werohia ranei, ka horoi tonu ki te nui o te wai, ka rapu atu ki te taote.
