We are  Isobutyl Acetate Technology Provider   and today we will introduce the technology of  Isobutyl Acetate Production . Isobutyl acetate, an esterified product of acetic acid and 2- butanol, is a colorless transparent liquid at room temperature. It dissolves with ethanol and ether, dissolves in water, flammable, and has mature fruit flavors. It is mainly used as a solvent for nitrocellulose and lacquer, as well as chemical reagents and spices. Isobutyl acetate has the typical properties of ester, including hydrolysis, alcoholysis, ammoniation, Grignard reagent and alkyl lithium addition, catalyzed hydrogenation and reduction of lithium aluminum hydride (lithium aluminum hydride), and the condensation reaction of Claeson ester (Claisen condensation) itself or with other esters. Isobutyl acetate can be qualitatively detected by hydroxylamine hydrochloride (NH2OH. HCl) and ferric chloride (FeCl). Other esters, acyl halides and anhydride will affect the inspection.

July 2018, Sichuan Leshan Fuhua Company's light formaldehyde concentration project. The installation and completion acceptance have been completed, and the test is now in the strip. Technology Introduction: In the production of paraformaldehyde and polyoxymethylene, high concentrations of formaldehyde are required as raw materials. But the normal formaldehyde production, whether it is silver or iron molybdenum, the product concentration is not more than 55%. So the need for raw materials for dehydration dehydration enrichment, and enrichment process will produce dilute formaldehyde. Dioformaldehyde is usually used to produce downstream products (such as urotropine, methylal, etc.) that are not required for formaldehyde feedstock concentrations and enrichment and recycling. Commonly used dilute formaldehyde concentration recovery technology there are two, respectively, decompression flash separation process and pressurized distillation enrichment process. The former in the co

There are two kinds of dilute formaldehyde concentration and recovery technologies commonly used, which are vacuum flash distillation separation and pressure distillation concentration. The former will again produce about 8% dilute formaldehyde in the process of concentration. The latter recycled get 36-46% formaldehyde solution, but in the process of pressure distillation, with the increase of pressure, formaldehyde disproportionation reaction to generate formate, this will not only cause loss of formaldehyde, more important is the serious corrosion of equipment, formic acid this problem using rank higher special steel can be used to solve, but investment will be too high, is not the economy. Our company can supply  Formaldehyde Concentration Technology  and  Formaldehyde Concentration Plant , welcome to contact us.

Phenol Alkylation  by phenol and olefin hydrocarbons, fatty alcohols, or made by chlorinated hydrocarbons by alkylation, it is important in the production of fine chemical intermediates, are widely used in surface active agent, antioxidant, paint, paint production. Its most of products are alkyl phenol epoxy ethane adduct, it is a kind of typical non-ionic surface active agent, acid and alkali resistance, oxidation resistance and stable chemical properties, such as widely used as the main ingredient in industrial detergent formulation, such as metal cleaner, also used as emulsifying dispersant, fabric finishing agent, pesticide, corrosion inhibitor, etc. Our company can provide  Phenol Alkylation Technology , if necessary, you can contact us.
