1. Investigation of acidic chemical recycling of poly(acetal-ester)s
Magister-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER
2. Developing Formaldehyde Free Flame Retardant for Cellulose
Magister-uppsats, Högskolan i Borås/Institutionen TextilhögskolanSammanfattning : Two organophosphorus compounds, namely diethyloxymethyl-9-oxa-10- phosphaphenanthrene-10-oxide (DOPAC) and diethyl (2,2-diethoxyethyl) phosphonate (DPAC) were applied on cotton cellulose to impart non-carcinogenic and durable (in alkaline washing) flame retardant property to it. Some acidic catalysts, sodium dihydrogen phosphate (NaH2PO4), ammonium dihydrogen phosphate (NH4H2PO4) and phosphoric acid (H3PO4), were successfully used to settle acetal linkage between cellulose and flame retardant (FR) compound.
