Title: Catalytic hydrogenation of nitro-aromatic explosive in alcohol soln. - at low temp. and hydrogen@ pressure, giving high yield without safety problems
Inventor: SCHOLLES HERBERT DIPL PHYS DR
IPC: C06B21/00
Filed: 1991-09-21
Abstract: Hydrogenation of nitro-aromatic explosives (I) is carried out in the presence of a solvent (II) and a catalyst (III) by continuous addn. of a soln. of (I) in (II) to a suspension of (III) in pt. of (II), kept in a reactor at a constant reaction temp. of ca. 40-100 deg. C and under elevated H2 pressure to maintain a max. (I) concn. in the reactor, (III) being sepd. after hydrogenation. (II) is an alcohol. The liq. reaction mixt. contg. (I) in a very low concn. of less than 50 mg/l is circulated by pumping at high speed and with a H2 gas charge kept at at least 20 vol.% by continuous injection of H2. The (I):(III) concn. ratio in the reaction mixt. is 1:(30-100), pref. 1:(50-70). USE/ADVANTAGE - The process is useful for hydrogenating e.g. trinitrotoluene (IA) to a prod. with min. residual (I) content. It avoids safety problems, since it operates at low pressure and temp., is economical and gives satisfactory yields, with negligible by-prod. formation. The prods. can be sepd. simply as chemically stbale salts by pptn. and filtration, avoiding the risk of decomposition. The process is suitable for continuous or batch operation

Title: Method for adjusting a pulsed electromagnetic valve
IPC: G05D7/06
Filed: 1993-02-22
Abstract: The invention relates to a method for adjusting a volume flow which flows through an electromagnetically actuated flow valve (4), as a function of a sample ratio of a pulse train (26) which is applied to the excitation coil (12) of the electromagnet (2). The electromagnet actuates a valve body (33), which is further loaded with force by a coil spring (20). Initially, a determination is made of the volume flow (25) which occurs at a predetermined sample ratio, whereupon this flow is set to a volume flow allocated to the predetermined sample ratio. According to the invention, for this purpose the opening time (t1) and the closing time (t2) of the valve body (3) are measured and, as a function of a difference existing from the times corresponding to the allocated volume flow (25), at least one force acting on the valve body (33) is altered, by which means the volume flow is adjusted to the sample ratio of the pulse train. <IMAGE>
