Propylene Tetramer (PTM)
Propylene tetramer (PTM), also known as dodecene, is an alkene. It is a C12 rich C11-13 olefin produced by the oligomerisation of propylene.
Propylene tetramer is the preferred name as this distinguishes it from other C12 molecules such as 1-dodecene and linear alpha-olefin derived from ethylene.
Janex offers various “cuts” of propylene tetramer from a broad cut with around 60% C12 content, to a narrow cut with over 90% C12 content.
Supply is performed either in parcel tankers or in iso-tanks.
Propylene Tetramer CAS 93821-12-6 / EC 298-697-1
CAS 6842-15-5 / EC 298-697-1
CAS 68526-58-9 / EC 298-697-1
By propylene oligomerisation using a solid catalyst (e.g. phosphoric acid (SPA), zeolites), polygas - a higher olefin liquid mixture – is produced.
Through a continuous or batch distillation, process various molecules can be extracted, one of them being propylene tetramer.
- Branched dodecylbenzene (also known as BAB or branched alkylbenzene)
- C12 iso-paraffin
- Dodecyl diphenyloxide sulfonate (surfactant for latex, rubber and textiles)
- Dodecylphenol (DDP
- Neotridecanoic acid
- Tert-dodecyl mercaptan (TDM)
- Tetrapropylene succinic anhydride or acid (anti-rust agent, curing agent for epoxy resin and intermediate)
