Summary:To provide a branched organopolysiloxane compound that has excellent compatibility with polar oils and the like and that can serve as a substitute for conventional low-molecular-weight siloxanes, and to provide a production method with which the branched organopolysiloxane is easily obtained at high purity.SOLUTION: A branched organopolysiloxane is represented by the following formula (1) (where R1 independently represents a C1-3 alkyl group, R2 represents a C2-3 alkyl group, R3 represents a C1-3 alkyl group. n represents 1 or 2, and m represents an integer of 0-3 with n=1, while m represents 0 or 1 with n=2. The bonding order of siloxane units may be block or random).SELECTED DRAWING: Figure 1 【課題】従来の低分子シロキサンの代替品となり得、極性油剤等との相溶性が良好な分岐型オルガノポリシロキサン化合物、及び前記分岐型オルガノポリシロキサンを簡便に高純度で得られる製造方法を提供する。【解決手段】下記式（１）TIFF2023150349000017.tif42126（式中、Ｒ1は、独立に炭素数１～３のアルキル基であり、Ｒ2は、炭素数２又は３のアルキル基であり、Ｒ3は、炭素数１～３のアルキル基である。ｎは１又は２であり、ｍは、ｎ＝１のとき、０～３の整数であり、ｎ＝２のとき、０又は１である。なお、シロキサン単位の結合状態は、ブロックであってもランダムであってもよい。）で表される分岐型オルガノポリシロキサン。【選択図】図１
