When the reaction time increased to 5 h, the hydrolysis side reaction was slightly increased and this situation was caused a slight increase to acid value
of the product.
, peroxide value and total polar components were determined before and after frying.
These properties include density, viscosity, flash point, cloud point, carbon residue and acid value
, and Mark-Houwink parameters in THF Polymer % Acid Mark-Houwink Mark-Houwink synthesized Yield value "a" "log K" Theo.
The shea oil acid value
obtained in this study is representative of samples from many trees.
This study revealed that the thiobarbituric acid value
increased with the increase in storage period of RP, but there was no significant effect of rancidity on the AME values of RP with the passage of storage time.
For example, a conversion of 99%, acid value
of 5 mg KOH/g by the reaction of adipic acid (5.
The oil is low in acid and free fatty acid value
Table 4: Properties of polyester polyols Sample Acid value
Hydroxyl value Number average molecular weight ([M.
Then the temperature was held at 180 [degrees] C for 4 h and finally raised to 200 [degrees] C and maintained until the acid value
reached about 30 mg KOH/g.
Ester value was obtained by finding the difference between the saponification value and the acid value
The polyols were characterized by determination of acid value
, oxirane number, hydroxyl value, molecular weight (GPC), and FTIR spectra.
5 percent, impurity is less than 1 percent, the Saponification-Number is 92-106mg KOH/g, acid value
is less than 9 percent, and Water-solubility hypo acidity is barely traceable or faintly alkali.
They are obtained from compositions comprised of carboxy-functional (meth)acrylic copolymers and/or polyesters, acid value
15-300, and epoxy-functional crosslinking agents dispersed or dissolved in continuous phase as specified, with usual additives, and optionally, polymeric polyols, other crosslinking agents and monoepoxide compounds.
It will be further elaborated by the BASF-YPC its acrylic acid value
chain with extra acrylic acid and butyl acrylate plants.
