| Abstract: | In order to determining melting point of antioxidant D and antioxidant BHT precisely, this paper involves three methods: the capillary without seal, the capillary with an opening and digital melting point measuring instrument. Results show the data gained by the way that involved the capillary without seal are precise and exact. And this method is convenient and economical. This paper also analysis the factors of effecting on determining melting point of antioxidant D and antioxidant BHT. |
