Selective Chain Scission of L-Lactide/ε-Caprolactone Chain Shuttled Copolymers. [PDF]

ChemSusChem
L‐lactide/ε‐caprolactone chain shuttled multiblock copolymers are composed of PLLA‐rich hard blocks and poly(ε‐caprolactone‐co‐L‐lactide) soft blocks. They can be selectively degraded, notably into PLA oligomers, by organocatalyzed transesterification. This allows not only to determine the block length but also to envision the recycling of the PLA part

Recyclable Lignin‐Based Thermadapt Shape Memory Polymers With Near‐Infrared Light Response

Advanced Functional Materials, EarlyView.
ABSTRACT Covalent adaptable networks (CANs) have been designed to address the recycling challenges associated with thermosets, while preserving their mechanical properties. However, producing biobased CANs with intelligent response capabilities remains challenging.

Methanesulfonic Acid as a Dual‐Role Reagent for Porous Polymer Network Design

Advanced Materials, EarlyView.
The design of porous polymer networks (PPNs) using methanesulfonic acid (MSA) as a dual‐role reagent facilitates the synthesis of robust PPNs for specific applications. It also makes the scale‐up process techno‐economically feasible because MSA functions simultaneously as both a solvent and a catalyst for the reaction.

Kinetic Study of Transesterification Reaction of Edible Oil Using Heterogenous Catalyst

Iraqi Journal of Chemical and Petroleum Engineering, 2022
   AlPO4 solid acid catalyst was prepared in order to use it in transesterification reaction of edible oil after supporting it with tungsten oxide. The maximum conversion of edible oil was obtained 78.78% at catalyst concentration (5gm.), temperature 70°

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

Advanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Production of Biodiesel from Chicken Frying Oil [PDF]

Pakistan Journal of Analytical & Environmental Chemistry, 2011
Chicken fried oil was converted into different biodiesels through single step transesterification and two step transesterification, namely acid-base and base–base catalyzed transesterification. Hydrochloric acid and potassium hydroxide with methanol were

Continuous Production of Biodiesel with Supercritical Methanol: a Simple Compressible Flow Model for Tubular Reactors [PDF]

, 2011
From an industrial point of view, the continuous process for biodiesel production with supercritical methanol (SCM) is more appropriate than the batch process.
