Rates and equilibria of ester hydrolysis: Combination of .

The hydrolysis reaction was carried out in a conventional 500 ml Parr autoclave, made of zirconium metal. The reactor consists of a feeding vessel, a reaction vessel, a heating unit, a stirrer and a sampling line. The sampling line was equipped with a cooling bath and a filter. The temperature control requires two thermocouples and cooling air.

Standard Hydrolysis Procedures

Standard Hydrolysis Procedure: The following is a vapor phase hydrolysis technique for multiple samples where samples are hydrolyzed in vial inserts that are placed inside a hydrolysis vessel. This is only one suggested method; there are numerous different methods in the literature. 1.

Study of Chemical and Enzymatic Hydrolysis of Cellulosic .

The objective of this study was to evaluate the chemical and enzymatic hydrolysis using a factorial experimental design (2 3 ) in order to obtain fermentable sugars from cellulose-based material (CBM) usually used as pet litter. In assessing chemical hydrolysis, we studied the effect of temperature, in addition to H 2 SO 4 concentration and reaction time, on the production of total .

Glass Linings | Pfaudler

One reason why our glass-lined reactors are trusted by over 90% of the world's top chemical companies is the sheer reliability of our reaction technologies. These technologies are critical to the safe containment of corrosive contents, maintaining the vessel pressure and ensuring the final batch quality.

Hydrolysis of acetic anhydride: Non-adiabatic calorimetric .

The hydrolysis of acetic anhydride was carried out with excess of water and in three different non-adiabatic vessels: (a) a cylindrical plastic vessel (reactor 1), (b) a volumetric flask (reactor 2), and (c) a thermal bottle or Dewar flask (reactor 3).
