What can sulfonic acid be used for?
Sulfonic Acid (LABSA) is a man-made chemical which is commonly used to manufacture detergents, water-soluble dyes, and catalysts, sulfonamide pharmaceuticals, and ion-exchange resins.
What is the formula for sulfonic acid?
A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O)2−OH, where R is an organic alkyl or aryl group and the S(=O)2(OH) group a sulfonyl hydroxide.
What is sodium naphthalene sulphonate?
Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete.
Is sulphonic acid a foaming agent?
Sulphonic acid is an organic acid, which is very important in liquid detergent production. It is one of the foaming agents for liquid detergent.
What is another name for sulphonic acid?
A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound is the hypothetical compound sulfurous acid. Salts or esters of sulfonic acids are called sulfonates.
Is sulfonic acid meta director?
It is a meta-directing group and a deactivating group because the −I effect of the group is quite strong and significantly outweighs that stabilization caused by conjugation (that you can describe with resonant structures).
What is poly naphthalene sulfonate?
Sodium Polynaphthalene Sulfonate – is a High Range Water Reducing Superplasticizer (Sodium Polynaphthalene Sulfonate). Sodium Polynaphthalene Sulfonate is made in powder and liquid form: in condition of brown water soluble powder or dark-brown water solution, which has the concentration of minimum 32%.
What is the HS Code for sodium naphthalene sulfonate?

How do you increase foam in soap?
Different oils give different amounts and different types of lathers, so many soap makers turn to sugar to increase the suds. Adding a bit of sugar to a soap recipe can help make a light, bubbly lather with large bubbles when the oils you’re using do not lather up as much as you’d like.
What is the functions of sulphonic acid in liquid soap?
Detergents and similar products like soap use sulfonic acid to break down the surface tension between water and grease, dirt, and other grime for a more effective clean.
How do you neutralize acid slurry?
The acid slurry is neutralized by a slow addition of caustic soda solution till it is neutralised. The pH of the solution is maintained and acid slurry is taken in plastic containers. Then known quantity of urea is added and kept for settling. Small quantity of perfume is added to liquid detergent before packing.
Does sodium hydroxide lower pH?
Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
Which is more reactive ortho para or meta?
Groups with an oxygen or nitrogen attached to the aromatic ring are ortho and para directors since the O or N can push electrons into the ring, making the ortho and para positions more reactive and stabilizing the arenium ion that forms. This causes the ortho and para products to form faster than meta.
What does meta directing mean?
Meta director: In electrophilic aromatic substitution, a substituent that favors electrophilic attack meta to the substituent. Most meta directors are also deactivators. Bromination of nitrobenzene gives meta-bromonitrobenzene as the major product because the nitro group is a meta director. aq.
What is sodium naphthalene formaldehyde?
SNF is a light yellow to yellowish brown powder, which is an anionic surfactant. It is widely used for the preparation of free-flowing and pumpable concrete mixture in the construction industry.
