    Notes: Abstract A partial cDNA which codes for the β-subunit of a plastidic chaperonin 60 (cpn60-β) from rye (Secale cereale L.) leaves was identified and sequenced, except for 46 amino acids of the N-terminus of the mature protein and the transit sequence. This is the first cpn60-β sequence determined for a monocotyledonous plant. Specific antibodies against cpn60-β were affinity-purified from an antiserum raised against the total soluble protein fraction of ribosome-deficient plastids. The localization of cpn60-β in chloroplasts or non-green plastids was confirmed by immunodetection in Percoll gradient-purified organelles. The expression and occurrence of cpn60-β was analysed by immunoblotting with the specific antibodies and Northern hybridization. The cpn60-β protein was constitutively expressed in various green and non-green tissues. It was evenly distributed along the major part of a rye leaf, while highest transcript levels occurred in the youngest and oldest leaf sections. The expression of the cpn60-β protein was not enhanced by a heat-shock treatment at 42 °C. The cpn60-β transcript and protein were more strongly expressed in various non-green, for instance etiolated, 70S-ribosome-deficient 32 °C-grown, or herbicide-bleached tissues, than in green leaves of rye. A rapid increase in the cpn60-β transcript level was also observed when green leaves were transferred from light to darkness while the protein level was not affected. The dark-induced increase in the cpn60-β transcript was totally suppressed in the presence of 2% sucrose. Inhibitor treatments suggested that the change in cpn60-β transcript level was not related to changes of the ATP supply of the tissue. While the large subunit of the photosynthetic protein ribulose-1,5-bisphosphate carboxylase was largely degraded during ripening of tomato fruits, high levels of cpn60-β were detected in tomato chromoplasts and in the yellow flower petals of Narcissus. Low levels of cpn60-β were detected in root tissue.

    Notes: A model for the phase distribution and evolution of the heterogeneous (suspension) polymerization of vinyl chloride is presented. Experimental information on pressure, temperature, and conversion has been obtained from a 34 liter bench reactor reproducing reaction conditions and product properties typical of industrial operation. A calculation procedure based on simple plant data is proposed for the description of the phase compositions and their evolution over the entire process. Results based on classical Flory-Huggins theory of solutions are presented and compared with existing data.

    Notes: The big success of the reaction injection molding (RIM) process has brought about a marked interest in reacting polymer processing. In the present work, we study the technical feasibility of a continuous process to coat metallic conductors using reacting polymers. In the envisioned system, RIM type reactants are mixed and then injected into a tubular reactor through the center of which we pass the cable to be coated. The predictions of the mathematical model developed show that a feasible process can be designed by adequate control of the heat transfer phenomena. The process needs in general, a low reactor temperature and a high cable temperature.

    Description / Table of Contents: Acyl- and Alkylidenephosphines. XXXII. Di-cyclohexoyl- and Diadamant-1-oylphosphine - Keto-Enol Tautomerism and StructureLithium dihydrogenphosphide · DME (1) [12] and cyclo-hexoyl or adamant-1-oyl chloride react in a molar ratio of 3:2 to give lithium di-cyclo-hexoylphosphide · DME and the corresponding diadamant-1-oylphosphide.2THF (1) resp. Treatment of these two compounds with 85% tetrafluoroboric acid. diethylether adduct yields di-cyclo-hexoyl- (1b) and diadamant-1-oylphosphine (1c). In nmr spectroscopic studies 1b over a range of 203 to 343 K, a strong temperature dependence of the keto-enol equilibrium is found; thermodynamic data characteristic for the formation of the enol tautomer (ΔH0 = -4.3 kJ. mol-1; ΔS0 = -9.2 J. mol-1. K (-1) are compared of 1,3-diketones.The enol tautomer of diadamant-1-oylphosphine (E-1c) as obtained from a benzene solution in thin colourless plates, crystallizes in the monoclinic space group P21/c {a = 722.2(2); b = 1085.5(4); c = 2434.8(5) pm; ß = 96.43(2)° at -100 ± 3°C; Z = 4}. An X- ray structure analysis (Rw = 0.033) shows bond lengths and angles to be almost identical within the enolic system (P—C 179/180; C—O 130/129; C—C(adamant-1-yl) 152/153 pm; C—P—C 99°; P—C—O 124°/124°; P—C—C 120°/120°; C—C—O 116°/116°. The geometry of the very strong, but probably asymmetric O‥H‥O bridge is discussed (O—H 120/130, O‥O 245 pm).
    Notes: Aus Lithium-dihydrogenphosphid · DME (1) [12] und cyclo-Hexoyl- bzw. Adamant-1-oyl-chlorid im Molverhältnis 3:2 zugängliches Lithium-di-cyclo-hexoylphosphid · DME und -diadamant-1-oylphosphid · 2THF 1) reagieren mit 85proz. Tetrafluoroborsäure · Diethylether-Addukt zu Di-cyclo-hexoyl- 1b) und Diadamant-1-oylphosphan (1 c). Die Lage des Keto-Enol-Gleichgewichts zwischen 203 und 343 K sowie thermodynamische Daten zur Bildung des Enol-Isomers ΔH0= -4,3kJ.Mol-1; ΔS0;=-9,2 J · mol-1 · K-1 () wurden NMR-spektroskopisch an einer 2 M Lösung des bei +20°C flüssigen Di-cyclo-Hexoyl-Derivates 1b in d8-Toluol ermittelt und mit Werten von 1,3-Diketonen verglichen.Das farblose, sich aus Benzol in dünnen Plättchen abscheidende Enol-Tautomer des Diadamant-1-oylphosphans (E-1 c) kristallisiert monoklin in der Raumgruppe P21/c {a = 722,2(2) b = 1085,5(4); c = 2434,8(5) pm; ß = 96,43(2)° bei - 100 ± 3°C; Z = 4}. Nach den Ergebnissen der Röntgenstrukturanalyse (Rw=0,033) weist das Molekül in beiden des Hälften des Enolrings nahezu identische Bindungslängen und -winkel auf P—C 179/180; C—O 130/129; C—C(Adamant-1-yl) 152/153 pm; C—P—C 99°; P—C—O 124°/124°; P—C—C 120°/120°; C—C—O 116°/116°. Die Geometrie der sehr starken, aber vermutlich asymmetrischen O‥H‥O-Brücke wird diskutiert (O—H 120/130; O‥O 245 pm).
