Description

Hydrazine sulfate is salt which generated by hydrazine and sulfuric acid, pure product is colorless scaly crystal or rhombic. The molecular weight is 130.12. Formula is N2H4·H2SO4. Melting point is 254℃, when continues heating, it can decompose. The relative density is 1.37. It is slightly soluble in water, soluble in hot water (at 20℃ 2.87, at 25℃ 3.41, at 30℃ 3.89, at 40℃ 4.16, at 50 ℃ 7.0, at 60℃ 9.07, at 80℃ 14.4), aqueous solution is acidic , it is insoluble in alcohol and ether. It is very stable in air. It is susceptible to alkali and oxidizing agents, it is incompatible with bases, oxidants. It has strong reduction. Rat oral LD50601mg/kg, it is toxic, carcinogenic. The main purpose of hydrazine sulfate is used for determination the weight of nickel, cobalt, cadmium, and the purification of rare metals, the separation of tellurium and polonium, as well as the precipitation of chlorate, hypochlorite and carboxyl compound, it is also used for manufacturing isoniazid , nitrofurazone, 100 Health hydrazine, anhydrous hydrazine, etc., it is also used as reducing agent, insecticides and sterilization agents. Hydrazine sulfate is nutritional supplement in United States for fighting against anorexia, weight loss and other symptoms patients which caused by cancer. Laboratory method for preparing hydrazine sulfate 1. Sodium hypochlorite is prepared by chlorine and sodium hydroxid, then reacts with ammonia to obtain hydrazine hydrate, and finally to obtain hydrazine by dehydration, and then reacts with sulfuric acid to obtain hydrazine sulfate products. Related chemical reaction equation is as follows: 2NH3 + NaClO → NH2Cl + NaOH NH2Cl + NaOH + NH3 → N2H4 + NaCl + H2O N2H4 + H2SO4 → N2H4 · H2SO4 2. When ammonia reacts with water, ammonium hydroxide can be obtained, and then by synthesis, hydrazine solution can be obtained, by evaporation, condensation, crystallization, and finally reacts with sulfuric acid to obtain hydrazine sulfate products.

Chemical properties

Production method

Urea method: Urea, sodium hypochlorite, caustic soda, in the presence of potassium permanganate can react, by distillation, and then reacts with sulfuric acid for neutralization, the resultant passes through cooling and crystallization, filtration, drying to obtain hydrazine sulfate products. NaOCI + NH2CONH2 + 2NaOH [KMnO4] → N2H4·H2O + NaCl + Na2CO3 N2H4·H2O + H2SO4 → N2H4·H2SO4 + H2O

Chemical Properties

colourless crystals or white powder

Physical properties

Colorless orthorhombic crystal; density 1.378 g/cm3; melts at 254°C; sparingly soluble in cold water 1.64% at 0°C and 3.41% at 25°C; more soluble inhot water; practically insoluble in alcohol (0.04% at 25°C).

Preparation

Hydrazine sulfate may be synthesized from aqueous ammonia and sodium hypochlorite solution in a two-step process. In the first stage, aqueous solution of ammonia is boiled with a normal solution of sodium hypochlorite in the presence of 10% gelatin solution to yield hydrazine. In the second stage, the hydrazine solution is ice-cooled followed by slow addition of concentrated sulfuric acid (Adams, R., and B.K. Brown. 1964. In Organic Synthesis, Collective Volume I, ed. H. Gilman and A. H. Blatt, 2nd ed. pp 309-310, New York: John Wiley & Sons). The reaction steps are as follows: 2NH3 + NaOCl → NH2NH2 + H2O + NaCl NH2NH2 + H2SO4 → NH2NH2 ?H2SO4

General Description

Hydrazine sulfate salt is a potential anticachexia agent for treating cancer patients.

Hazard

A carcinogen (OSHA).

Carcinogenicity

Hydrazine and hydrazine sulfate are reasonably anticipated to be human carcinogens based on sufficient evidence of carcinogenicity from studies in experimental animals.

Purification Methods

Its solubility in H2O is 3% at room temperature, but is very soluble in hot H2O. It is a suspected carcinogen. [Adams & Brown Org Synth Coll Vol I 309 1941, Audrieth & Nickles Inorg Synth I 90 1939.]

Check Digit Verification of cas no

The CAS Registry Mumber 10034-93-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10034-93:
(7*1)+(6*0)+(5*0)+(4*3)+(3*4)+(2*9)+(1*3)=52
52 % 10 = 2
So 10034-93-2 is a valid CAS Registry Number.

Process for producing ketazine by reacting a ketone with ammonia and a peroxide

-

, (2008/06/13)

Ketazines having the general formula (I) STR1 wherein R1 represents alkyl group having 1 to 4 carbon atoms and R2 represents (i) an alkyl group having 1 to 4 carbon atoms or (ii) a phenyl group optionally substituted with an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms or a halogen group, and R1 and R2 together with the carbon atom to which they are both bonded may form a ring, are advantageously manufactured by reacting an aliphatic or aromatic ketone having the formula (II) STR2 wherein R1 and R2 are as defined above, with ammonia and a peroxide compound or compounds in the presence of amorphous silica or palladium compounds, as a catalyst, at a temperature of from 0° to 120° C., in a liquid phase.
