Folasaga

Methyl 2-bromomethyl-3-nitrobenzoate.

Tulaga lelei:

1. Fa'aaliga: vai e leai se lanu po'o se tioata paepae pa'epa'e;

4. Malosi: e uiga i le 1.6-1.7 g / ml;

5. Solubility: soluble i solu organic, e pei o ava malosi, ethers ma ketones.

Fa'aaogā:

Methyl 2-bromomethyl-3-nitrobenzoate e masani ona faʻaaogaina e avea o se vaeluaga o vailaau faʻasaina, e mafai ona faʻaaogaina i le tuʻufaʻatasia o vailaau faʻasaina e pei o le methyl besylsulfonylcarboxyl, ma e mafai foi ona faʻaaogaina e avea o se vailaʻau faʻapipiʻi o le glyphosate.

Metotia:

Methyl 2-bromomethyl-3-nitrobenzoate e mafai ona saunia e le chloromethylation ma le nitrification. O laasaga faʻapitoa e faʻapea: methyl benzoate e tali atu i le acetic acid ma le phosphorus trichloride i le maualalo o le vevela e maua ai le methyl 2-chloromethylbenzoate; Ona tuʻuina atu lea o le methyl 2-chloromethylbenzoate i totonu o le vaega nitro e ala i le faʻamaʻiina o le nitrate taʻitaʻia e tuʻuina atu ai le methyl 2-bromomethyl-3-nitrobenzoate.

Fa'amatalaga Saogalemu:

1. Methyl 2-bromomethyl-3-nitrobenzoate e mu i le maualuga o le vevela ma le mumū, o lea e tatau ai ona aloese mai le maualuga o le vevela ma le mumū.

2. Fai matatioata puipui ma totigilima pe a fa'aoga e 'alofia ai le pa'i i le pa'u ma le manava o kasa.

4. Pe a teuina, e tatau ona faʻamaufaʻailogaina ma taofia mai le vevela, afi ma mea faʻamaʻi.
