Information of 26171-83-5
Hi ,friend.I am chelsea,working in a chemical trade platform; come here by accident.I am glad to be here.Now let me share you something,I hope you will need it.
Name:1,2-Butanediol;α-Butylene glycol Molecular formula : C4H10O2 MW : 90.12 CAS :26171-83-5 nature : the boiling point is 192-194 °C,94 °C-96 ° C (1.6kPa), 68 ° C (0.053kPa), relative density is 1.019 (0 / 4 ° C), the refractive index is 1.4375. Water soluble. Preparation : derived from epoxy butane hydration. Heat 0.1% sulfuric acid solution to 60 ° C and add 1,2 - epoxy-butane in an hour. In order to react ,keep heating at 60-70 ° C for 0.5 h, and add 40% Alkali Solution Ionic to pH7-7.5, decompression steamed to the water, and then distillation, collection of 110 ° C (3.72kPa) derived products distillate yield over 80%. purposes : for organic synthesis and Preparation of 2-amino butanol .

Suggestion
Poly Aluminium Chloride for drinking water is a great product of the processes for glass-lined equipment because of its high-intensity corrosive effect. Poly Aluminium Chloride known as (PAC) is a basic water inorganic polymer with a formula of [Al2(OH)nCl6-nLm] that indicates the polymerization and shows the degree of PAC products and its solutions.
The product has a general strong absorption rate. While the process takes place where the hydrolysis process, precipitation condensation, and absorption all occur at the same time. That means the chemical and physical processes happen simultaneously. The structure of the poly aluminum chloride for drinking water is comprised of polycarboxylic complex and the mix of variable morphology creating high speeds of precipitation which immediately enhances the purification effect of wide PH range and no corrosion in the pipeline effect. Further, it can effectively remove Suspended Solids(SS), Chemical Oxygen Demand(COD), remove chromatics and Biochemical Oxygen Demand as well. The Product has high applications for different products such as medication, chemicals and for shoes as well. But it's high usage is for the treatment of drinking water and wastewater. Where PAC Poly Aluminum Chloride is Used? PAC is an inorganic Polymer that is created from the aluminum mineral powder and hydrochloric acid. The core purpose of the product is water purification and many companies use it to purify water at minimum cost. For water purification, it is mostly supplied to industrial companies, water RO plants, and water purification companies and runs under the industry-government set standards to provide 100% effectiveness. As for the water itself, PAC is rarely corrosive and also does not affect the purifying equipment. This allows the equipment to stay intact and reduce its maintenance cost and damages allowing for better purification. The product acts fast in sterilizing, removing fluorine, oil, heavy metallic salt and deodorize, etc. Hence remove any externalities. Product Commercial Usage: bleaching and dyeing, refractory materials adhesive paper sizing printing and dyeing sugar liquor refined cosmetics and other industries, cement accelerator precision casting and many more It is evident that globally very few water purification formulas have been created and aluminum in the form poly aluminum chloride has been used and is still being incorporated into the removal of bacteria from freshwater. The common bacteria being found is cyanobacteria or phosphorus. However, before it has been tested there have been various sample testing done on nature and artificial freshwater to understand its implications and effects on the ecosystem. Various results stated the effects on the ecosystem were based purely on the standard ISO methods which lacked sufficient data as the unavailability of nontarget species was missing. A singular treatment cannot always work for all water types. Water can be acidic depending on the geographical location and its minerals which is why a clear understanding is essential. If not then the right amount of poly aluminum chloride cannot be added which could further hinder the water minerals. |
