摘要： Provided is free cutting alloy excellent in machinability, preserving various characteristics as alloy. The free cutting alloy contains: one or more of Ti and Zr as a metal element component; and C being an indispensable element as a bonding component with the metal element component, wherein a (Ti,Zr) based compound including one or more of S, Se and Te is formed in a matrix metal phase. The free cutting alloy is more excellent in machinability, preserving various characteristics as alloy at similar levels to a conventional case. The effect is especially conspicuous, for example, when a compound expressed in a chemical form of (Ti,Zr)4C2(S,Se,Te)2 as the (Ti,Zr) based compound is formed at least in a dispersed state in the alloy structure.

摘要： A free-cutting Ni-base heat-resistant alloy excellent in the high-temperature strength and corrosion resistance was proposed. The alloy contains Ni as a major component, 0.01 to 0.3 wt % of C and 14 to 35 wt % of Cr, and further contains at least one element selected from Ti, Zr and Hf in a total amount of 0.1 to 6 wt %, and S in an amount of 0.015 to 0.5 wt %. The alloy has dispersed in the matrix thereof a machinability improving compound phase, where such phase contains any one of Ti, Zr and Hf as a major constituent of the metal elements, essentially contains C and either S or Se as a binding component for such metal elements. The alloy also satisfies the relations of WTi+0.53WZr+0.27WHf>2WC+0.75WS and WC>0.37WS, where WTi represents Ti content (wt %), WZr represents Zr content (wt %), WHf represents Hf content (wt %), WC represents C content (wt %) and WS represents S content (wt %). This successfully suppresses the amount of free S residing in the alloy, which results in an improved machinability while preventing the hot workability from being degraded.

摘要： The carbonyl group at the 2-position of levoglucosenone is reduced to obtain a hydroxyl group having a .beta.-configuration. The hydroxyl group having a .beta.-configuration is reversed to an .alpha.-configuration, and hydroxyl groups are added at the 3- and 4-positions in a cis-.alpha. form. Finally, the protective group of the hydroxyl group at the 2-position is eliminated. The reduction of the carbonyl group at the 2-position can be performed such that the levoglucosenone is reacted with aluminum lithium hydride or sodium boron hydride in an appropriate solvent. Reversion of the hydroxyl group having a .beta.-configuration can be performed by the Mitsunobu method or a method having a mesylation step and a step using cesium acetate. The addition of the hydroxyl groups to the 3-and 4-positions in the cis form can be performed by oxidizing the double bond across the 3- and 4-positions with an appropriate oxidizing agent. The elimination of the protective group of the hydroxyl group at the 2-position can be performed under basic conditions in accordance with normal methods. According to the method of the present invention, D-allosan can be obtained stereoselectively in high yield via a smaller number of steps than that of the conventional synthesis method.

摘要： In the method of the present invention for manufacturing 3-DPA-lactone, a protective group is introduced in the first step into the hydroxyl group at 4-position of .gamma.-ribonolactone by an ordinary method. Then, an acid anhydride or an acid chloride is added in the presence of a tertiary amine compound so as to conduct a .beta.-elimination of the hydroxyl group at the 3-position. As a result, a double bond is formed between the 2- and 3-positions and, at the same time, the hydroxyl group at the 2-position is acylated. The double bond between the 2- and 3-positions is reduced in the next step by means of a catalytic hydrogenation. Finally, the protective group of the hydroxyl group is eliminated by an ordinary method. The particular method permits using readily available raw materials, decreasing the number of manufacturing steps, and easily and selectively synthesizing the desired 3-DPA-lactone, which is hardly obtained from nature in a large amount, in high yield, compared with the conventional method.
