Uses. 3-Pentenenitrile, 3PN, is used entirely by the manufacturers to make adiponitrile. i7j -2-Pentenenitrile, 2PN, can be cycli2ed catalyticaHy at high temperature to produce pyndine, a solvent and agncultural chemical intermediate. 2PN is also chlorinated to manufacture pentachloropyndine, an intermediate in the insecticide Dursban produced by Dow. Addition of ammonia to 2PN foUowed by reduction leads to 1,3-pentadiamine (Dytek ep), which is used as a curing agent for epoxy coatings and as a chain modifier in polyurethanes. [Pg.226]

A research team led by O. Figovsky synthesized aliphatic multifunctional cyclic carbonates from corresponding epoxies and carbon dioxide and NIPUs based on them [17,18], The authors tested some compositions polyfunctional carbonates synthesized in the laboratory, namely trimethylolpropane tricyclocarbonate (TMPTCC) and chlorine-contained aliphatic tricyclocarbonates (on the base of chlorine-contained aliphatic epoxy resins Oxilin ) and various diamines 2-methylpentam-ethylene diamine (MPMD), Dytek A, Invista Co. meta-xylenediamine (MXDA), Mitsubishi Gas Chem. Co. polyetheramineJeffamineEDR-148, Huntsman Co. and diethylenetriamine (DETA), D.E.H. 20, Dow Chemical Co. The properties of these materials are shown in Table 4.1. [Pg.154]

An alternative route to y9-picoline (3) involves a two-step conversion of2-methyl-l,5-pentanediamine (or Dytek A 17) to 3-methylpiperidine (18) over zeolite MFI [42]. This reaction is believed to be in commercial operation in China. a-Picoline (2) can be produced by converting either phenol (19) [43] or aniline (20) [44] over MFI at elevated temperature and pressure. This so-called ben-zamine rearrangement is discussed in Section 5.2. [Pg.279]

Primary aliphatic diamines are very important intermediates in polymer industry. Tetramethylene diamine is a monomer for polyamide 4,6. Hexame-thylene diamine is used in two main industrial productions. Copolymerisation with adipic add gives rise to nylon 6,6. Reaction with phosgene leads to isocyanates which are monomers for painting industry. Methylpenta-methylene diamine is a monomer for thermoplastics (DU PONT s DYTEK). [Pg.291]
