What is the alloy catalyst

Bimetallic catalyst is often referred to as the alloy catalyst. In its actual form is not necessarily the alloy reaction conditions. Normally consists of active metal and noble metal alloy catalyst, it can show a kind of metal is another kind of metal dilution geometry or group effect, and electronic interaction of the ligand effect. Such as Pt catalyst after joining Sn or Re alloying, can improve the alkane dehydrogenation cyclization and aromatization activity and stability. Add Ir Pt catalyst make naphtha reforming under low pressure, and increase the heavy distillate oil generation. I add Cu Ni alloying of cyclohexane dehydrogenation activity remains unchanged, but can significantly reduce the activity of hydrogen solution of ethane.

Eat zinc phosphide may have what harm

Zinc phosphide, gray crystalline powder, insoluble in water and alcohol, soluble in acid, benzene and carbon disulfide. In the 1100 ℃ sublimation in hydrogen. Room temperature in phosphorus bad smell in the air, but I don't catch fire. Encounter water and damp air will slow decomposition, encounter acid is intense decomposition emits poisonous phosphine gas, easy to catch fire. Contact with the nitric acid by oxidation and explosion.
Zinc phosphide wasn't use raticide and insecticide, fumigation refinement is the crystallization of dark grey ribbon luster, often with mixture poison bait use food. Eating poison bait, rodents or the zinc phosphide to stand the unclean food, cause poisoning, decomposed into phosphine in the stomach, highly toxic, can irritate the stomach corrode action. Zinc phosphide inhaled, on cardiovascular, liver, kidney, has strong toxicity to stimulate the nervous system.
After eating zinc phosphide, decomposed into phosphine in the stomach, highly toxic, corrosion can irritate the gastrointestinal function, ecg, liver, kidney, nervous system has strong toxicity of stimulation, the longer the higher mortality rate. Must urgently vomiting, with soap and water and clean water to rinse the skin and eyes, there is no specific antidote.

What is the nature and role of carrageenan

Carrageenan is white or light brown granular or powder, odourless or slight odor, taste is executed. About 80 ℃ water soluble in, forming sticky, transparent or light milky liquid solution. Such as ethanol, glycerol, or first saturated sucrose solution soaked, and is more easily dispersed in water. With 30 times solution of water to boil for 10 min after cooling gel. Combined with water viscosity increases, the reaction with protein emulsification, emulsion stability.
Carrageenan, stretching carageen glue, antlers algin, Irish moss glue, is composed of galactose and dehydration galactose polysaccharide sulfate calcium, potassium, sodium, ammonium salt. Because different sulfate combining form, production of 7 kinds of main types of carrageenan, k - type, ι - types, lambda - dominated, gamma, parameter types, factors, types, mu - types.
Based on the properties of carrageenan has, in the food industry usually it is used as thickener, gelling agent, suspending agent, emulsifier and stabilizer, etc. And the production application of carrageenan and its rheological properties are larger, and accurately grasp the rheological properties of carrageenan and its change rule under various conditions is of great importance to production.

Side effects of Pirenzepine

What side effect does Pirenzepine have? Pirenzepine's indications: for gastric ulcer and duodenal ulcer, stress ulcer, acute gastric mucosal bleeding. Because the curative effect compared with H2 receptor antagonists and proton pump inhibitors, the clinical application of less. Pirenzepine; of pharmacology:Pirenzepine is the selective ML receptor antagonist, has a high affinity for ML receptors on parietal cells, smooth muscle, myocardium and salivary glands M2 receptor affinity is very low, so the amount of general treatment only can inhibit gastric acid secretion of pupil, gastrointestinal tract, heart, salivary gland is not obvious, only large doses can cause dry mouth, blurred vision, heart adverse reaction rate. Patients with duodenal ulcer were treated with oral administration of 25mg/, 3 /d, and the basal gastric acid secretion was reduced by 4 after the first 51% weeks, and the secretion of gastric acid stimulated by gastrin was reduced by about 41%, which was about five. It can inhibit the secretion of pepsin. The drug has little effect on the pH of gastric juice, mainly to reduce the secretion of gastric juice.
 

How to detect the enzyme naringinase
