Is benzenesulfonyl chloride soluble in water?
Solubility : Soluble in alcohol, diethyl ether, ether, and benzene. Insoluble in cold water.
What is benzene sulphonyl chloride also known as?
Benzene sulphonyl chloride (C(6)H(5)SO(2)Cl) is called Hinsberg’s reagent. It is used for the distinction between primary, secondary and teriary amines. It is also used for separation of primary, secondary and teritiary amines from their mixture. (
What happens when benzyl sulfonyl chloride is treated with water?
* Benzene Sulfonyl Chloride reacts with WATER to form toxic and corrosive gases.
How is benzene sulphonyl chloride obtained?
Benzenesulfonyl chloride can be prepared by the action of phosphorus pentachloride on benzenesulfonic acid or its salts;1 by the action of phosphorus oxychloride upon the salts of benzenesulfonic acid;2 by the action of chlorosulfonic acid on benzene3 or sodium benzenesulfonate;4 and by the action of sulfuryl chloride …
What does benzenesulfonyl chloride react with?
It is a colourless viscous oil that dissolves in organic solvents, but reacts with compounds containing reactive N-H and O-H bonds. It is mainly used to prepare sulfonamides and sulfonate esters by reactions with amines and alcohols, respectively….Benzenesulfonyl chloride.

How does the Hinsberg test work?
In the Hinsberg test, an amine is reacted with benzene sulfonyl chloride. If a product forms, the amine is either a primary or secondary amine, because tertiary amines do not form stable sulfonamides. If the sulfonamide that forms dissolves in aqueous sodium hydroxide solution, it is a primary amine.
Which is Heisenberg reagent?
benzene sulfonyl chloride
Hinsberg reagent is an alternative name for benzene sulfonyl chloride. This name is given for its use in the Hinsberg test for the detection and distinction of primary, secondary, and tertiary amines in a given sample. This reagent is an organosulfur compound. Its chemical formula can be written as C6H5SO2Cl.
How is sulfonyl chloride made?
Aromatic sulfonic acids and sulfonyl chlorides can be prepared by sulfonation of benzene derivatives with fuming sulfuric acid and chlorosulfonic acid, ClSO3H, respectively, while aliphatic sulfonic acids are prepared by vigorous oxidation of thiols or by reaction of amine sulfur trioxide complexes (e.g., Me3NSO3) with …
Why do tertiary amines not react with benzene sulphonyl chloride?
Tertiary amines do not hold active hydrogen, and thus they don’t react with benzene sulphonyl chloride.
Why is product formed by diethylamine with benzene sulphonyl chloride?
Primary amine (ethylamine) react with benzenesulphonyl chloride to form N-ethylbenzenesulphonamide, which is soluble with alkali, through the formation of salt.
How do you do a Hinsberg test?
Procedure for Hinsberg Test [4,5]
- Add 8-10 drops of amine to a large test tube.
- Add 10 drops benzene sulfonyl chloride.
- Add 10 mL 10% NaOH.
- Shake vigorously to mix (use a cork)
- Check for the presence of a single layer (primary amine) or a double layer (secondary amine) in the solution.
Which reacts with Heisenberg reagent?
Ethyl methylamine and diethylamine are secondary amines. They react with Hinsberg reagent to give base insoluble product.
What is Hinsberg test?
The Hinsberg reaction is a test for the detection of primary, secondary and tertiary amines. In this test, the amine is shaken well with Hinsberg reagent in the presence of aqueous alkali (either KOH or NaOH).
What is a sulfonyl chloride?
1.5 Sulfonyl Chlorides Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents.
What is the density of sulfuryl chloride?
1.67 g/cm³Sulfuryl chloride / Density
Why is product formed by diethyl amine with benzene sulphonyl chloride not soluble in aqueous solution?
Since N, N-diethylbenzene sulphonamide does not conains any hydrogen atom attached to nitrogen atom, it is not acidic and hence insoluble in alkali.
What is action of benzene sulphonyl chloride on different amine?
The reaction of the benzene sulfonyl chloride with primary amines gives a sulfonamide product that is soluble in alkali. This reaction can be illustrated as follows. The reaction of the benzene sulfonyl chloride with secondary amines gives a sulfonamide product that is NOT soluble in alkali.
How do you distinguish primary secondary and tertiary amines by benzene sulphonyl chloride?
The Hinsberg test, which can distinguish primary, secondary, and tertiary amines, is based upon sulfonamide formation. In the Hinsberg test, an amine is reacted with benzene sulfonyl chloride. If a product forms, the amine is either a primary or secondary amine, because tertiary amines do not form stable sulfonamides.
How do you prepare phenylsulfinic acid from sulfonyl chloride?
Preparation. Phenylsulfinic acid can be prepared in several ways, most easily through reduction of sulfonyl chlorides with zinc dust or iron. However other starting materials can be used. Due to the air sensitivity of this compound it is often formed as a salt.
What is the chemical name of phenylsulfinic acid?
From Wikipedia, the free encyclopedia Phenylsulfinic acid is an organosulfur compound with the formula C 6 H 5 SO 2 H. It is a colorless or white crystalline solid that is usually stored in the form of its sodium salt. In aqueous solution it is strongly acidic and is easily oxidized in air.
What is the molecular weight of benzenesulfonyl chloride?

What happens when phenylmethanesulfonyl chloride reacts with methylene chloride?
92-94 °C (lit.) Phenylmethanesulfonyl chloride is an aliphatic sulfonyl chloride. It reacts with triethylamine in methylene chloride or ether to yield trans-stilbene and cis diphenylethylene sulfone. Its reaction with 1,1-bis(diethylamino)ethane has been studied.
