Rapid pyrolysis of wood block by microwave heating

Masakatsu Miura, +4 more
- 01 Mar 2004 - 
TL;DR: In this article, the pyrolysis of cylindrical wood blocks (diameter: 60-300 mm; weight: 80-12 000 g) by microwave irradiation has been studied using two microwave ovens (1.5 and 3 kW).
Journal ArticleDOI

Diphenyl Phosphate as an Efficient Cationic Organocatalyst for Controlled/Living Ring-Opening Polymerization of δ-Valerolactone and ε-Caprolactone

Kosuke Makiguchi, +2 more
- 07 Mar 2011 - 
TL;DR: In this article, a ring-opening polymerization of δ-valerolactone and e-caprolactone (e-CL) using 3-phenyl-1-propanol (PPA) as initiator and diphenyl phosphate (DPP) as the catalyst in toluene at room temperature with the [δ-VL or e-CL] 0/[PPA]0/[DPP] ratio of 50/1/1 homogeneously proceeded to afford poly(α-βαβββ ββ
Journal ArticleDOI

Convenient synthesis of high molecular weight poly(succinimide) by acid-catalysed polycondensation of l-aspartic acid

Masayuki Tomida, +3 more
- 01 Sep 1997 - 
TL;DR: Polysuccinimide (PSI) was synthesized by acid-catalysed polycondensation of l -aspartic acid as discussed by the authors at a reaction temperature of above ca. 160°C, and a PSI with the highest weight-average molecular weight, 64 300, was obtained using a mixed solvent of mesitylene and sulfolane (w/w, 7 3 ).
Journal ArticleDOI

Diphenyl Phosphate as an Efficient Acidic Organocatalyst for Controlled/Living Ring-Opening Polymerization of Trimethylene Carbonates Leading to Block, End-Functionalized, and Macrocyclic Polycarbonates

Kosuke Makiguchi, +4 more
- 25 Feb 2013 - 
TL;DR: In this paper, the ring-opening polymerization (ROP) of cyclic carbonates with diphenyl phosphate (DPP) as the organocatalyst and 3-phenyl-1-propanol (PPA) as an initiator has been studied using trimethylene carbonate (TMC), 5,5-dimethyl-1,3-dioxan-2-one, 5, 5-5-dibromomethyl- 1, 3-Dioxan)-2,1,1.
Journal ArticleDOI

Synthesis and thermoresponsive property of end‐functionalized poly(N‐isopropylacrylamide) with pyrenyl group

Qian Duan, +6 more
- 01 Feb 2006 - 
TL;DR: In this article, a pyrenyl 2-chloropropionate (PyCP) was used as the initiator and CuCl/tris[2-(dimethylamino)ethyl]-amine (Me 6 TREN) as the catalyst system.
