Filed: 2002-03-22
Granted: 2003-07-27
Abstract: FIELD: organic chemistry, chemical technology. SUBSTANCE: invention proposes method for preparing poly-alpha-olefins. Method is carried out in two successively arranged reactor of flow-type filled with granulated aluminum oxide as a solid sorbent subjected for thermovacuum treatment preliminary. Alpha-olefins are passed through the first reactor at elevated temperature and pressure and prepared oligomerizate is cooled and BF 3  is desorbed from them by passing through the second reactor in the amount 100 volumes of oligomerizate per 1 volume of sorbent, not less. Then process is carried out in reverse direction, i. e: alpha-olefins are passed through the second reactor and obtained oligomerizate is passed through the first one with the following alternated feeding into the first or the second reactor under above indicated conditions and after desorption of BF 3  the end product is isolated from oligomerizate by rectification. Thermal treatment of granulated aluminum oxide is carried out at temperature 150-250 C under vacuum and then cooled up to temperature 20-60 C and treated with gaseous BF 3  under excessive pressure 0.1-1.2 MPa. Reaction of oligomerization is carried out at temperature 40-160 C under pressure 0.5-0.7 MPa using C 8 -C 14 -alpha-olefins. Oligomerizate is cooled at reactor outlet up to temperature 30-50 C followed by isolation of poly-alphaolefins with viscosity value 3.5-4.2 mm 2 /s/s at 100 C as the end product. The proposed method ensures preparing poly-alpha-olefins with required viscosity value designated for using as basic components of lubricating oils and provides using excessive amount of unreacted BF 3  completely without any loss and to exclude using co-promoters, in part, oxygen as in the known method.

Inventor: KORCHAGIN V I
IPC: C02F1/52
Filed: 2002-04-19
Granted: 2003-05-20
Abstract: FIELD: rubber industry. SUBSTANCE: treatment of waste waters containing non- coagulated latex and polydisperse polymer particles is accomplished by adding Cao-Mgo-containing coagulant, coagulation, and removal coagulated particles, said coagulant being saturated solution of Cao-Mgo originated from building materials production as waste or ill-conditioned materials. Polymer-to- coagulant ratio (calculated for solids) is 1:(0.2-0.4). Waste is used until full consumption of Cao-Mgo is attained. When preparing saturated coagulant solution, latex-freed waste water is used in amounts depending on coagulant consumption. Proposed process allows coagulant consumption to be substantially decreased as well as it allows reducing secondary contamination of waste water with various contaminants and inert impurities and obtaining coagulated polymer suitable as elastic additives in manufacture of mechanical rubber ware, ebonites, roofing materials, and pavements.
