FORM AS APPLIED IN THE TEST (if different from that of starting material)
OTHER SPECIFICS: - Key result
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- The melting point of aluminium trititanium dodecachloride was tried to measure by DSC. No endothermal peak which might show melting point was not observed. Only exothermic peak was observed at around 229 C.
The titianium trichoride is known to have crystalline polymorphs, alpha, beta, gamma and delta form.
This substance has the least stable delta crystalline form to increase polymerisation activity. Thus the peak observed for DSC analysis is attributed to the exothermic peak to change its more stable crystalline form. - Executive summary:
The melting point of aluminium trititanium dodecachloride was not observed by DSC. Only exothermic peak was observed at around 229 C, which may be attributed to crystalline transform of titianium trichloride.

- Conclusions:
- Thermal analysis on aluminum trititanium dodecachloride was carried out with TG/DTA (Thermal gravity/Differential Thermal Analysis). Weight loss was observed at around 310 °C with gradual endothermal peak. Judging from this measurement, the decomposition temperature of aluminum trititanium dodeca chloride was determined to be around 310 °C.
- Executive summary:
The decomposition temperature of aluminium trititainium dodecachloride was around 310 °C, which was determined by thermal analysis, TG/DTA.
Referenceopen allclose all
Exothermic peaks were observed as follows;
run 1 229.83 C
run 2 227.79 C
Average 228.81 C
This peak is due to the crystal transform from delta-form to other crystal form such as alpha, beta or gamma form)
Small weight loss (1.98%) was observed at 128.2 °C and about 22 wt% weight loss was observed at from 307.4 to 318.9 °C. The latter weight loss might correspond to removal of aluminum chloride of which theoretical content in this substance is 22.4 wt%.
Description of key information
DSC study using aluminum trititanium dodecachloride showed exothermic peak at around 230 °C. TG/DTA study showed obvious weight loss at around 310 °C. It is known for titanium trichloride to have crystalline polymorphs. This product is manufatured for polymerisation initiator and has least stable gamma crystalline form. The peak observed in DSC analysis seemed to be crystalline transformation temperature. In TG/DTA analysis, from 307 to 319 °C some amount weight loss of sample was observed. Thus decomposition temperature of aluminum trititanium dodecachloride was determined to be about 310 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 310 °C
Additional information
Aluminim trititanium dodecachloride decomposes at 307 - 320 °C. This material also transforms its crystalline form at around 230 °C.
