The existing modern technology for synthesizing Cetyl Palmitate usually entails esterification under a driver such as focused sulfuric acid. Concentrated sulfuric acid has strong oxidizing, drying out, water-absorbing and acidic properties. Using it as a stimulant can easily trigger several side reactions (such as oxidation, carbonization, polymerization). etc), so the selectivity is poor, and a large quantity of waste fluid is created, which pollutes the setting. In recent times, there have been research study records on utilizing molecular filters, not natural salt very acids, heteropoly acids, and strong acids as drivers for esterification responses. These approaches have actually offseted the drawbacks of the sulfuric acid technique to a certain level, but they likewise have complex procedure procedures and production and prep work cycles. Long haul trouble.
There is an existing method for preparing Cetyl Palmitate. Cetyl alcohol and hexadecanoic acid are combined according to a molar proportion of 1: (0.8-1.2) and heated up to a liquified state. After mixing evenly, the mixture is cooled down to space temperature; after that, the cooled mix is Warmth to 150-350 ° C under an inert environment and maintain the temperature level for 25-35 mins to prepare Cetyl Palmitate.
This approach straight makes use of cetyl alcohol and cetyl ester as resources. Initially, the cetyl alcohol and cetyl ester are melted and blended to develop a binary mix, and then the cetyl hexadecyl alcohol is gotten through a heat therapy reaction in an inert environment. The prep work technique of today invention The raw products made use of are cheap and simple to obtain, the reaction conditions are basic, the procedure is easy, the price is low, and it appropriates for industrial production. In addition, the entire response of the here and now invention only uses cetyl alcohol and cetyl ester as resources, without including any type of catalyst, no side responses will certainly take place, no byproducts will contaminate the atmosphere, and the expense of resources is low.
The reaction temperature level is set in the range of 150-350 ° C, which not just makes certain that the reaction is fully performed and high yield is acquired, yet additionally does not influence the return due to also low response temperature, and at the same time avoids item volatilization and low return triggered by too high temperature level.
The whole reaction is carried out under an inert environment, which avoids the response of basic materials with air or other impurities airborne and ensures the purity of the item.
