松香是由一系列氢化菲结构的三环二萜一元树脂酸组成。我国年产松香70多万吨，居世界第一位。 杂环化合物是碳环化合物的环链上含有一个或多个非碳原子的有机化合物。在已知的有机化合物中，杂环化合物的数量占65％ 以上，其主要是含氮、氧、硫等原子的系列衍生物，广泛应用于农药、香料加工、医药、化工等社会生活领域。松香树脂酸结构中羧基和菲环经改性可得松香基杂环化合物，主要有酯、喹啉、咪唑、呋咱、吲哚、咪唑啉等系列衍生物，并应用于化工、生物农药及医药等领域。 [ Last edited by jim5362 on 2009-12-5 at 20:14 ] |

A series of hydrogenated rosin is composed of tricyclic diterpene resin acid. China's annual output of rosin more than 70 million tons ranks first in the world. Heterocyclic ring care compounds of carbon chain that contains one or more non-carbon atoms in organic form. In the known organic compounds, heterocyclic compounds account for more than 65%, which are mainly nitrogen, oxygen, sulfur atoms such as a series of derivatives widely used in pesticides, spice processing, pharmaceutical, chemical, and other social spheres of life. Rosin resin acid ring structure through the modification of carboxyl group and the philippine through available rosin-based heterocyclic compounds. They are mainly esters, quinoline, imidazole, furazan, indole, and imidazoline derivatives, which have desired applications in chemical, biological pesticides and medicine and other fields. |
