The Chemical Properties of NEOCUPFERRON

NEOCUPFERRON Use

Sensitive reagent for measuring deposited copper and iron.

The Production Method of NEOCUPFERRON

Dissolve 137g of 1-nitronaphthalene in 4235ml of 95% ethanol, cool to 0°C, and pass in ammonia gas to distill, and then pass in hydrogen sulfide until it is filled with yellow ammonium sulfide crystals. Place it under cooling for 24 hours, pour it into a large amount of cold water, and filter out the white 1-naphthylhydroxylamine precipitate. Dissolve the base in 1500 ml of ether, extract and wash with water, and separate the water layer. Under cooling, pass ammonia gas into the ether layer, while adding butyl nitrite dropwise (65g butyl nitrite is required for 100g 1-naphthylhydroxylamine). After the reaction is complete, filter with suction, wash the filter cake with ether, dissolve the filter cake in methanol, and add ether to precipitate a precipitate. Repeat this several times to obtain pure copper iron spirit.

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
