Chemicals aquisition
Hello,
looking to complete my hobby lab and have found a seller who sells also the more "advanced" reagents and solvents.
He has not everything from my "wish list" and not always the amount I was looking for but some good stuff indeed.
Would you say the pricing is ok?
Names are in German on the list, so please forgive my laziness to translate everthing correctly), prices are converted into EUR, amounts in g,kg or
ml, l.
3-Methyl-1-Butanol 1l 10,03
4-Nitrobenzoic Acid 250g 5,73
Aluminiumchlorid anhydrous 100g 2,87
Ammoniumnitrat 100g 5,60
Aniline 100ml 2,87
Bariumhydroxid 250g 7,64
Benzoic acid 1kg 12,42
Benzene 3l 18,63
Lead (IV)-acetate 500g 35,82
Bromine 500ml 7,16
Chrom (IV)-oxide 500g 9,55
Cyclohexane 800ml 8,36
Dichlormethane 3l 17,91
Dimethylformamide 3l 37,25
Acetic anhydride 2l 31,04
Hydroflouric Acid 70% 2l 23,88
Potassium Chlorate 100g 1,55
Methylenblue 50g 5,97
Methylethylketon 1l 9,31
Methylorange 50g 9,07
Methylred 100g 3,34
Sodium 500g 27,46
Sodiumborohydrid 250g 41,79
Sodiumflouride 100g 4,06
Sodiumnitrite 2kg 18,63
Naphtalin 500g 18,15
n-Hexan 1l 26,51
Pentaerhytrit 1kg 24,84
Phenolphtalein 100g 14,09
Perchloric Acid 70% 500ml 39,40
Phenole 1kg 15,52
Phosphor red 500g 35,82
Phosphorpentachloride 1kg 55,88
Tetrachlormethane 1l 24,84
Tetrahydrofurane 2l 37,25
tert-Butanol 1l 27,94
All in all some 700 EUR.
The bromine seems ridicuolusly cheap, but it's only technical grade as he noted. Otherwise most should be lab or even reagent grade.
Also he mentioned that the Hydroflouric Acid is brown. Anyone have a clue? Haven't found a hint what that could be. Maybe it was used for rust removal
and it is Ironoxide contamination? I guess I have to ask for that once more.
Thank you in advance.

In general, the pricing of these chemicals is very good, or even ridiculously cheap. E.g. 500 g sodium for EUR 27 or so is fantastic. The list also
contains some very hard to obtain items, such as PCl5.
I would take everything from this list, except the HF. Do you really want dirty brown 70% HF around in your house? Please stay away from that if you
value your health. You certainly don't want to distill this to make it pure again.
If the bromine is low grade, no problem. Distill it. Bromine is very easy to distill if you have glass apparatus, I have done several times. It is
fantastic to have 500 ml for that price, even if it is impure.

At those prices you should buy two of everything and stock my lab too. ;-)
Seriously, those are some serious chemicals at fantastic prices. I have to concur with woelen on all points.

I just had a friend that moved to Germany because his wife is in the military. I might have to get him to do some shopping for me.

Thank you very much for the input.
To set the record straight, actually it is in Poland. I live not far away from the Polish border.
As for the HF I will reconsider, knowing how dangerous HF is. I already have some 20% solution, also technical but clear. Nevertheless I'll ask him
what this contamination is just out of curiousness.
Also thanks for the tip with the bromine. Of course I have good ole German Schott NS29 destilling equipment.
P.S. Make no mistake, without proper contacts most hazardous chems are very hard to get in todays Germany too. Conc. H2SO4 or reagent grade HNO3 65%
are no problem at all here. Red phosporous and iodine neither. But benzene for example is nearly impossible to get without contacts for normal
citizens.

Germany is going to restrict the 65% nitric acid at some point as it
is an EU directive. I would assume Poland will too, unless both
countries say this doesn't make sense and thumb their nose at the
directive.

Yes, I read about that EU-directive which is already effective in GB. Read also that Germany makes an exception here, can not find the link. I can
still order 1l of reagent grade 65% HNO3 for EUR 10,99 in Chemnitz/Germany. 5l for EUR 47. Of course circumstances are probably subject to change,
that's why I already accumulated some liters.

Thanks again for the input.

That would be nice, but I don't speak the language.
