Kita tidak hanya memiliki cukup HI; 1,56 mol untuk mengurangi 0,5 mol efedrin hidroklorida, tetapi kelebihan 0,185 mol H3PO2. Strongly heating hypophosphorous acid will cause the hypophosphorous acid to decompose and form phosphine. anhidrat magnesium sulfat dapat digunakan. 4-IODOPYRIDINE-2-CARBOXYLIC ACID 3,5-diisopropylphenol cmtirust agent T-708 Sodium hypophosphite TRIS(2,2'-BIPYRIDYL)RUTHENIUM(II) CHLORIDE HEXAHYDRATE XANTHURENIC ACID. The acid is prepared industrially via a two step process. Bilas anhidrat magnesium sulfat dengan sedikit eter (atau toluena) setelah pengeringan solusi eter/amina utama. The formula for this acid is generally written H 3 PO 2, but a more descriptive presentation is HOP(O)H 2, which highlights its monoprotic character. Inorganic chemists refer to the free acid by this name (also as "HPA") although its official IUPAC name is phosphinic acid. Many translated example sentences containing "hypophosphorous acid" – French-English dictionary and search engine for French translations. Bentuk asam hypophosphorous murni kristal putih yang meleleh pada 26,5 ° C Struktur elektronik asam hypophosphorous adalah sedemikian rupa sehingga hanya memiliki satu atom hidrogen terikat pada oksigen, dan dengan demikian itu adalah asam oksi monoprotik. It is a weak acid and forms only one series of salts, the hypophosphites. Hypophosphorous acid, also known as phosphinic acid, is a chemical compound. Sekarang karena rasio Ephedrine: HI adalah 1: 3 = (3/1), kami membutuhkan 0,75 mol HI untuk setiap 0,25 mol efedrin hidroklorida. It is also used as a polymerization catalyst and polycondensation. Ini untuk mengurangi skala kecil P-diumpankan ke methamphetamine. Api atau ledakan berada pada risiko yang lebih tinggi saat memasak apa pun di atas 10 gram, menggunakan prosedur ini. Copyright ©2020 I Love Translation. As a sequestering agent, it helps in the binding of divalent cations. Rasio untuk H3PO2: I2 adalah 1:1, sehingga hanya 0.78 mol H3PO2 diperlukan untuk bereaksi dengan mol 0,78 I2 untuk membentuk 1,56 mol HI. Setelah penambahan I2, lembut panas sehingga gas HI berkembang dari kondensor, tambahkan 5 ml ramuan dari H2O bawah kondensor sampai gas HI berhenti berkembang dan karenanya jumlah maksimum HI kejenuhan disimpan dalam larutan ini dicapai. Asam murni dapat diperoleh dengan ekstraksi larutan oleh dietil eter. The method is an improvement in that reaction time is shortened and … HYPOPHOSPHOROUS ACID 50% (H3PO2) CAS No. Hypophosphorous acid. Ada tidak ada metode bodoh-bukti keamanan ketika bekerja dengan bahan kimia alam ini, kecuali peralatan laboratorium yang tepat, dll yang digunakan; dan ini masih tidak tidak elimanate bahaya, hanya mengurangi kemungkinan bahwa kecelakaan akan terjadi.Jika seseorang ingin memiliki 5 gram sebagai peoduct mereka selesai, dari 6-8 gram P-makan.
