The present disclosure relates to a plasticizer composition characterized in having alkyl groups derived from an isomer mixture of hexyl alcohol with the degree of branching of less than 2.0 as a cyclohexane triester. When the plasticizer composition is applied to a resin, stress resistance and mechanical properties may be maintained to equal or better levels, migration and loss properties and plasticization efficiency may keep balance, and light resistance and heat resistance may be markedly improved.

The present invention discloses a crystalline aluminum phosphite, a preparation method thereof and an application thereof as or for the preparation of a flame retardant or a flame retardant synergist. The preparation method has the following processes: 1, reacting aluminum hydrogen phosphite with an aluminum-containing compound in water at 80-110° C. to obtain a precipitate in the presence of no strong acid or a small amount of strong acid; 2, washing and filtering the precipitate; 3, drying the precipitate at 100-130° C.; 4, continuously heating the dried solid step by step at a low speed, where the material temperature is increased to not exceeding 350° C. from room temperature at about 5-10 h, with a temperature rise rate not exceeding 5° C./min. Compared with amorphous aluminum hydrogen phosphite, the crystalline aluminum phosphite has a higher thermal decomposition temperature, lower water absorption and weaker acidity, and can be synergistic with diethyl aluminum hypophosphite to achieve better flame retardant property and thus, is used for a halogen-free flame retardant component of high polymer materials.
