p-Toluene sulfonic acid monohydrate

p-Toluene sulfonic acid monohydrate

p-Toluene sulfonic acid monohydrate

Desc ription

p-toluene sulfonic acid monohydrate is an organic-soluble acid catalyst in organic synthesis. The catalyst has been incorporated in the esterification of carboxylic acids or transesterification of esters. The compound has been used as a reducing agent for the reductive amination of ketones and aldehydes. In the presence of p-Toluene sulfonic acid monohydrate novel deazaflavin-cholestane hybrid compounds have been synthesized in a condensation reaction. 2-Phenylethyl alpha-glucoside has also been synthesized in the presence of p-Toluene sulfonic acid monohydrate.

Safety assessment of xylene sulfonic Acid

Safety assessment of xylene sulfonic Acid

Safety assessment of xylene sulfonic Acid

xylene sulfonic acid, toluene sulfonic acid, and alkyl aryl sulfonate hydrotropes used in cosmetics as surfactants, hydrotropes, were reviewed in this safety assessment. The similar structure, properties, functions, and uses of these ingredients enabled grouping them and using the available toxicological data to assess the safety of the entire group. The Cosmetic Ingredient Review Expert Panel reviewed relevant animal and human data related to these ingredients. The panel concluded that xylene sulfonic acid and alkyl aryl sulfonate hydrotropes are safe as cosmetic ingredients in the present practices of use and concentrations as described in this safety assessment, when formulated to be nonirritating.

Sodium Xylene Sulfonate

Sodium Xylene Sulfonate

Sodium Xylene Sulfonate

sodium xylene sulfonate is an effective coupling /hydrotrope for water solutions of various surfactants and hydrophylic solvents.Sodium xylene sulfonate is used in liquid detergent.They are effective in promoting the compatibility of various ingredients present in a multi-component system.It is used as an electroplating bath additive and as viscosity reducer for concentrated liquid detergent and as solubilizer and cloud point depressor.SXS (Sodium Xylene Sulfonate) is commonly used as a hydrotrope.Since SXS has no detergency, Amphoteric or Phosphate Ester surfactants which contribute both detergency and hydrotroping power to the cleaner are used in high performance formulations.

Synonyms:Xylenesulfonic acid, sodium salt;

Chemical Formular:C8H9NaO3S

Molecular Weight:208.21

CAS Number 1300-72-7

Specification - 40% solution

Appearance:Liquid

Purity (%):40 min.

Inorganic Matter (%):1.5 Max

Packing:200kg plastic drum

Switching power supply

Switching power supply

switching power supply

You all know how a typical linear power supply operates: A heavy transformer takes the line voltage and converts it into something slightly above the desired final voltage. Some diodes rectify it, a big filter capacitor smoothes out the DC, and a series pass transistor burns up the excess voltage, so you get the desired output. A simple control circuit drives the pass transistor to hold the output voltage constant. The circuit is simple and uses few parts, but several of these parts are big, heavy, and expensive. And the efficiency is usually only around 50%, often even lower. That produces a lot of heat, which must be removed by big heat sinks and fans.

The switching approach is totally different: The line voltage is directly rectified and filtered, resulting in about 300 or 150V DC (300 is more commonly used). This feeds a power oscillator which produces output at about 20 to 500 kHz. This relatively high frequency allows the use of a small, lightweight and low cost transformer to reduce the voltage. The output is then rectified and filtered. And now comes the most interesting feature: Instead of just burning up the excess energy, in the switching power supply the control circuit steers the power oscillator in such a way that it delivers just the amount of energy needed. So, very little energy is wasted, resulting in high efficiency (75 to 90%), almost no heating, and a much reduced electricity bill!
