We determine the resonant parameters of the vector states $\phi(1680)$ and $\phi(2170)$ by doing a combined fit to the $e^+e^- \to \eta\phi$ cross sections from threshold to $2.85~{\rm GeV}$ measured by BaBar, Belle, BESIII and CMD-3 experiments. The mass $(1678^{+5}_{-3} \pm 7)~{\rm MeV}/c^2$ and the width $(156 \pm 5 \pm 9)~{\rm MeV}$ are obtained for the $\phi(1680)$, and the mass $(2169 \pm 5 \pm 6)~{\rm MeV}/c^2$ and the width $(96^{+17}_{-14} \pm 9)~{\rm MeV}$ for the $\phi(2170)$. The statistical significance of $\phi(2170)$ is $7.2\sigma$. Depending on the interference between the $\phi(1680)$, $\phi(2170)$ and a non-resonant $\eta\phi$ amplitude in the nominal fit, we obtain four solutions and $\Gamma^{e^+e^-}_{\phi(1680)}\cdot \BR[\phi(1680)\to\eta\phi] = (79 \pm 4 \pm 16)$, $(127\pm 5 \pm 12)$, $(65^{+5}_{-4} \pm 13)$ or $(215^{+8}_{-5} \pm 11)~{\rm eV}$, and $\Gamma^{e^+e^-}_{\phiy}\cdot \BR[\phi(2170)\to\eta\phi] = (0.56^{+0.03}_{-0.02} \pm 0.07)$, $(0.36^{+0.05}_{-0.03} \pm 0.07)$, $(38 \pm 1 \pm 5)$ or $(41 \pm 2 \pm 6)~{\rm eV}$, respectively. We also search for the production of $X(1750)\to \eta\phi$ and the significance is only $2.0\sigma$, then we determine the upper limit of $\Gamma^{e^+e^-}_{X(1750)}\cdot \BR[X(1750)\to\eta\phi]$ at 90\% confidence level.

In this talk we summarize the results we obtained for the partial decay widths of ϕ(2170) into two-body final states formed by a K̄ and a Kaonic resonance, like K(1460), K1(1270), as well as to final states constituted by a ϕ and an η/η´ mesons. The results obtained are compared with the values extracted from experimental data on the corresponding branching ratios, which were determined by the BESIII collaboration. A reasonable agreement is found, which together with the previous reproduction of the mass, width, and cross section for the process e+e− → ϕ f0 strongly indicates the molecular nature of ϕ(2170) as a ϕKK̄ system.
