Paragraph 0015-0017, (2021/06/12)
The invention belongs to the field of pharmaceutical chemicals, and particularly relates to a novel process for synthesizing a tetramethylguanidine product. The synthesis process of tetramethylguanidine comprises two main processes of chlorination reaction and condensation reaction, and the existing production process is an intermittent production process and is produced in batches. In the reaction process, an organic solvent needs to be used for extraction and purification for many times. The preparation process is complicated, the yield is low, the requirement on production equipment is high, the cost is high, and the safety and environmental protection are poor. The intermittent production process of tetramethylguanidine is continuously transformed, so that the yield is increased, and the safety, environmental friendliness and intelligence of the production line are improved; besides, the continuous transformation of the tetramethylguanidine production process has important practical significance.

, (2010/12/30)
The present invention has its object to provide a curable composition which comprises a guanidine compound as a non-organotin type catalyst, is less discolored, has good surface curability, depth curability, strength rise and adhesiveness, and can retain the curability even after storage; the above object can be achieved by a curable composition which comprises: (A) an organic polymer containing a silyl group capable of crosslinking under siloxane bond formation, the silyl group being a group represented by the general formula (1): -SiX 3 (1) (wherein X represents a hydroxyl group or a hydrolyzable group and the three X groups may be mutually the same or different), (B) a guanidine compound (B-1) as a silanol condensation catalyst, and (C) a plasticizer, wherein the content of the component (B-1) is not lower than 0.1 part by weight but lower than 8 parts by weight per 100 parts by weight of the component (A), and a non-phthalate ester plasticizer accounts for 80 to 100% by weight of the (C) component plasticizer.
