Title: Susanna M. Karpacheva: Patents in Epoxy Resin and Lignocellulose Processing.

Introduction

Susanna M. Karpacheva is an inventor associated with Moscow, Russia. Her patent work includes processes for preparing epoxy resin and equipment for producing lignocellulose materials. The supplied information lists 2 patents.

Latest Patents

Karpacheva’s listed patents address chemical processing and the treatment of plant-based materials.

“Process for Preparing Epoxy Resin” describes a method for producing epoxy resin from epichlorohydrin and 2,2-bis(p-hydroxyphenyl)propane. The process first combines the ingredients with a small amount of alkali and solvent at a controlled temperature to form a homogeneous mass. More alkali is then added, and the mixture undergoes polycondensation under stirring to produce the resin.

“Reaction Vessel with Pulsating Means for Producing Lignocellulose” describes an apparatus for processing materials such as chips, sawdust, chopped plants, bark, and small fibres. Its vertical column contains perforated plates arranged in a zigzag pattern, which helps increase the contact time between coarse raw materials, oxygen-containing gas, and alkaline reagent. A pulsating mechanism moves the liquid reagents vertically, while guide vanes direct some of their flow horizontally through the plates.

Career Highlights

The two listed inventions reflect work on distinct industrial challenges: preparing epoxy resin through controlled chemical reactions and designing equipment for lignocellulose production. Together, they demonstrate an interest in process conditions, material handling, and apparatus design.

Collaborations

The supplied information identifies Mikhail A. Markevich and Anatoly I. Nepomnyaschy as Karpacheva’s coworkers. No company name is provided.
