Temat: oczyszczanie NBS przez krystalizację
Witam!

Wg. "Purification of laboratory chemicals" NBS mozna oczyszczac nastepujaco:
"N-Bromosuccinimide  [128-08-5] M  178.0, m 183-184O(dec).
N-Bromosuccinimide (30 g)  was dissolved rapidly in 3OOmL of boiling water
and filtered through a fluted filter paper into a flask immersed in an
ice-bath and left for 2h.The crystals were filtered, washed thoroughly with
ca lOOmL cold water and drained on a Buchner funnel before drying under vac
over P2O5 or CaC12 [Dauben and McCoy JAm Chem Soc 81, 4863, 1959]. Has also
been crystd from acetic acid or water (10 parts, washed in water and dried
in vacuo,

BTW do tej pory nie probowalem zadnej z opisanych metod ;)

Witam. Mam kilka kg starego NBSu (ÂżóÂłty i Âśmierdzi bromem). Jak go
najlepiej
oczyÂściĂŚ? PróbowaÂłem krystalizacji z wody, ale na zimno nie ma
zauwaÂżalnych
efektów (ÂżóÂłty jak przed krystalizacjÂą, a powinien byĂŚ biaÂły), natomiast
na
gorÂąco rozkÂłada siĂŞ z wydzieleniem bromu. Org. Synth. podaje krystalizacjĂŞ
z
gorÂącej wody albo z kwasu octowego jako dobrÂą metodĂŞ oczyszczania...
Czy ktoÂś z Was to robiÂł?
Pozdr.,
MK

Bardzo dobrze ze o tym napisales! Indianie poludniowoamerykanscy juz od bardzo
dawna walcza o uszanowanie ich tradycji! A ponizej przesylam jakie wlasciwosci
odkryli w lisciu koki naukowcy z Harwardu... indianie utrzymuja ze jesli na
ziemi pozostalyby tylko dwie rosliny koki i guinua wystarczylyby kompletnie zeby
odzywic organizm czlowieka. i dziwia sie niezmiernie ze "mlodszy brat"(tak mowia
o bialych) zamiast zakonczyc z glodem na swiecie przerabia swieta roslina na
uzywke ktora zabija. jak to mowia: " mlodszy brat jeszcze do tej pory nie
zrozumial ze przyszedl tutaj zeby sie uczyc a nie zeby nauczac"
NUTRITIONAL PROPERTIES OF COCA LEAF
Thanks to an investigation realised by the University of Harvard in 1975 called
'The Nutritional Value of Coca Leaf', it has been proved that the daily chewing
of 100 grams of coca leaf satisfies the alimentary ration recommended for
adults, while 60 grams per day fulfills the recommended daily intake of calcium.
In the same way, new investigations have been initiated in the proof of its
scientific usefullness in biomedicine and pharmacy.

Its contents in vitamins and other elements mean that coca tea constitutes a
nutritive complement of the daily diet. In the same studies of the University of
Harvard it has been asserted that from 100 grams of Coca there are nearly two
grams of Potassium, which is necessary for the equilibrium of the heart.
Potassium has also been shown to have slimming properties.

Knowing that these teas are so rich in these nutrients, they become both a food
source and medicine.

EACH 100 GRAMS OF COCA LEAF CONTAINS:

Toal Nitrogen 20.06 mg.
Total involatile Alchaloids 0.70 mg.
Fat 3.68 mg.
Carbohydrates 47.50 mg.
Beta Carotene 9.40 mg.
Alpha caroteno 2.76 mg
Vitamin C 6.47 mg
Vitamin E 40.17 mg.
Thiamine (vitamin B1) 0.73 mg.
Riboflavin (Vitamina B2) 0.88 mg.
Niacin (factor p.p.) 8.37 mg.
Calcium 997.62 mg.
Fosphate 412.67 mg.
Potassium 1.739.33 mg
Magnesium 299.30 mg.
Sodium 39.41 mg.
Aluminium 17.39 mg.
Barium 6.18 mg.
Iron 136.64 mg
Strontium 12.02 mg.
Boron 6.75 mg.
Copper 1.22 mg.
Zinc 2.21 mg.
Mangnesium 9.15 mg.
Chromium 0.12 mg.

Thinking about the elimination of the coca plant is therefore nonsense, as this
is an imposition on the elemental principles and rights of the ancient cultures
that have used the coca leaf as a fundamental basis for their cosmovision and
traditional knowledge, as well as great qualities such as its nutritional
qualities (comparable with milk or soya) and therapeutic qualities.

Now that the terrible ecological consequences for flora, fauna and mankind that
the forced erradication of the Coca cultivations has caused - in particular
fumigations with glysophate - are being revealed, we present this alternative to
take the coca in its pure and natural form to the cities and to treat various
pathologies.

The aim is to commercialize coca leaf as an aromatic tea in its completely
natural form, without being subjected to any processing or treatment. It is
simply dried, ground down and packed into a small bag of filter paper. Its
consumption does not have any alterative effects. These aromatics are consumed
in other countries like Peru and Bolivia, under the name of Mate and are freely
for sale in the airports.
