Beschreibung
3-(1-Pyridinio)-1-propanesulfonate is a white crystalline powder used to prepare electroplating additives.It has good thermal qualitative and chemical stability, and its mechanical strength is also very good. The low polymer molecular weight is prone to disproportionation and cross-linking reactions.
Chemische Eigenschaften
White to Off-White Solid.
Verwenden
3-(1-Pyridinio)-1-propanesulfonate can be used:
- As a Bronsted acid ionic liquid catalyst in combination with H₂SO₄ and H₃PO₄ for the dehydration of glycerol to acrolein via semi-batch reaction technique.
- As a catalyst in the form of sulfonated heteropoly acid salts for the synthesis of isoamyl isovalerate.
- In the preparation of molybdenum imido alkylidene NHC catalysts, which are used in biphasic olefin metathesis.
- To prepare water-stable SO₃H-functionalized Br?nsted acidic task-specific ionic liquids (TSILs).
Verwenden
3-(1-Pyridinio)-1-propanesulfonate is a non detergent sulfobetaine used as a mild solubilizing and stabilizing agent for halophilic malate dehydrogenase, halophilic elongation factor Tu (hTu), pig heart malate dehydrogenase, chicken egg w hite lysozyme and E. coli beta-galactosidase. Preserves the antigenic conformation of serine protease gp76. Does not interfere with colorimetric assays using p-nitrophenylphosphate and o-nitrophenyl -b-D-galactopyranoside as substrates. Reduces aggregation and significantly improves protein renaturation. Zwitterionic over a wide pH range. Does not absorb significantly in the near-UV range. Ca n be easily removed by dialysis.
Verwenden
Stronger leveling agent in nickel electroplating
Application
3-(1-Pyridinio)-1-propanesulfonate is used in the preparation of electroplating additives,and it is used in medicine and daily chemicals.
Hazard
3-(1-Pyridinio)-1-propanesulfonate is irritating to the eyes and skin, especially the eyes, and may cause respiratory irritation in a single exposure. It may also cause specific target organ toxicity.
Synthese
In the equipped with a stirrer, thermometer, Calcium chloride drying tube and dropping funnelNecked flask was charged with 6.10 g (0.05 mol)1, 3-propanesultone and150 mL of ethyl acetate was added and stirred until 1, 3-propanesultone was dissolved, The flask was heated to 60 ° C in an oil bath equipped with methyl silicone oil, A solution of 5.14 g (0.065 mol) of pyridine was slowly added dropwise50 mL of ethyl acetate, After the completion of the dropwise addition (dropwise time: 30 min)Insulation reaction 2h, Pressure filtration, The residue was washed with ethyl acetate, Vacuum drying, To give N- (3-sulfonic acid) propylpyridine as an internal salt (Py-PS) 8.64 g, The final product is 3-(1-Pyridinio)-1-propanesulfonate.
